100% is a, typically used, redundant expression. Corre=ct would be just Het.

using albino as the example being a recessive trait, a het would come from an albino bred to either a normal or a het albino. The babies that look normal would be het for albino since one parent had two albino genes and had to pass one on to each of it's offspring.

The percentage hets come form breeding het to het. Gennetivally it would produce:

1/4 albino
1/4 het from dad
1/4 het from mom
1/4 both normal genes

Since the bottom three all look the same, each is a 2/3 probability of being het or 66% Actually closer to 67%

There are also 50% hets which come from het bred to normal.

14.19 BCI
And those are only the breeders

lots.lots.lots feeder mice and rats

ok so there is no 100% het?what do you get if you mixed a normal to a 100% het albino?

This stuff is really confusing. =/

100% hets- albino and a normal

66% hets- 2 het albinos

50% hets- het. albino and a normal

Try googling the punnett square or just learn how to do a dihybrid cross and your set for awhile

Bob

thanks that much clearer....

so if you take a normal and an albino how mnay albino baby's would you get?

and if you mix a het albino to a normal... would you get any albinos?

Albino X Normal produces a litter of Heterozygous for Albino animals.

A Het Albino X Normal produces a 50-50 split of Hets and Normals. You can't tell the difference so we say they have a 50% chance of being hets.

ok so how do you make an albino? 2 hets? or what if you put 2 albinos together do you get either all normals or all abinos?

You can make an Albino from one of three ways.

Albino X Albino = Albino

Albino X Het = Albino and Hets

Het X Het = 1/4 Albinos, 1/2 hets and 1/4 normals.

whoa that helps alot... thanks alot chris

Animals are either Heterozygous, Homozygous or neither for any given mutation.

When a Homozygous animal is bred to a non-gene carrier all the offspring are Heterozygous (100%).
A Het X Homozygous produced half a litter of Homozygous and half a litter of Heterozygous animals (100% hets).

The 66% possible hets and 50% possible hets denote the chance those animals statistically have of being heterozygous.

A Het X Het pairing will produce 1/4 Homozygous animals. The remaining 3/4 of the litter are 2/3 hets and 1/3 non-carriers. Because 2/3 of those are hets, but you can't tell which ones are, we say they have a 66.6% Chance of being hets, aka they are 66% possible hets.

Breeding a Het X non-carrier produces statistically 1/2 hets and 1/2 non-carriers. Because you can not differentiate between the two we say that the offspring have a 50% possible chance of being hets.

ok so if you have 50% het.... theres a 50% chance that it doesnt carry it?

100% het means there is no question about it the animal is a het.

66% het means it came from a het X het breeding and has a 2/3 chance of being a het.

50% het means it came from a het x non-carrier breeding and has 1/2 chance of being a het.

Yes!

A 50% het means that the animal has a 50% chance of being a het and a 50% chance of not being a het.

However marketing an animal as having a 50% chance of not being a het isn't going to make is too appealing!

ok so how do you make an albino? 2 hets? or what if you put 2 albinos together do you get either all normals or all abinos?

You should really google punnett square or dihybrid cross and spend 30 minutes and you'll understand (I was in your position like a month ago and I can see clearly nowlol)

2 het albinos

25% albinos
50% het albino
25% totally normal looking

further simplified as
25% albino
66.7% chance of the rest of the offspring will carry this recessive gene but the litter may be albino het heavy or normal heavy but you won't know which is which but these are only probabilities

Bob

lol ok ill do that rigth after this last question....

How mnay albinos if any do you get from a 100% albino to a normal.... 50% will be Albino?

You lost me on the wording but since albinism is recessive both carriers have to be carrying the gene is you want to see that in the clutch so

Albino and a normal
one carries aa the albino + the normal AA
only one carrier so visual morphs in the clutch just hets
100% hets.
further simplified as het. albino

co-dominant means it only has to be het. for the visual morph
ex. motley, arabesques, hypo, jungle, and PROVEN pastels or from a reputable breeder or line of pastels.

the het forms of the co-dominant morphs are the regular forms and the homozygous co-dominant morphs are the supers mm-super motley
hope it helps

Bob

what do you get if you mix a 100% het albino to a normal is what i was saying. Do you get any albinos from it?
-----

aim-lizz710
lizliz710@yahoo.com

No, you get half normals and half het albinos. All offspring are labeled as 50% possible hets.

ooooh.. thanks everybody. i sorta understand it now.

NOOOOOOOOOOOOO
Albinism is recessive so therefore both parents need to carry the trait.

het. albino and a normal is this
50% normal looking
50% het. albino
and these are only probabilities so you won't know Dick from Jane hahahalol

You can find an albino for as little as $500 on up. I would buy an albino male so you won't have to deal with a big albino female and let it mate with a female, I don't know if u got a male or female norm already but I would get a male and let him knock up your female and mate the female keepers from that litter back to the father and there are your albinos

male albino and female het. albino gives you
50% albinos
50% het. albinos
no totally normal anythings but don't further inbreed further than that because the albino gene is not strong enough. So by breeding your unrelated normal female to your male albino you would be outcrossing yours a little more but the dad would be knocking up his daughters so to speak haha...

Bob

i have a normal female so i need a male... Shes not ready to breed just yet so i still got time to look around.

have a big ol genetics thread.

If you already have a NORMAL female and want to produce a morph, Then you have two options for your male:

If you want to see morphs in one generation, you'll HAVE to go with a dominant or codominant morph.

If you're willing to wait TWO generations, then you can go with any of the morphs, recessive, dominant or codominant

Terms:
Gene = the basic unit of genetics, Genes come in pairs, one supplied from each parent. Each gene pair determines one specific trait. There are thousands of gene pairs in each strand of DNA.

Mutant gene = any gene that is different from the corresponding normal gene. Not necessarily a visual mutation.

Wild type or normal = A snake that looks like most of the snakes found in the wild. Also used to describe any individual gene that when paired up with a similar gene would produce a snake that, for that individual gene trait, would look like most of the snakes found in the wild.

Heterozygous (slang - heterozygous) = having two different genes within a gene pair. Most commonly one normal and one mutant but could be two different mutant genes.

Homozygous (slang - Homo) = having both genes within a gene pair the same. Can be normal or mutant.

Super = Slang term commonly used when a snake has a gene pair that is Homozygous for either a dominant or a codominant mutant gene.

Trait = Physical appearance that it distinguishable from the normal physical appearance.

Recessive mutant gene = Trait is only expressed when the gene pair is Homozygous for the specific mutant gene.

Dominant mutant gene = A mutant gene that has it trait expressed when the gene pair is either heterozygous or Homozygous for that specific mutant gene. Heterozygous and homozygous specimens are not 100% distinguishable from each other. Note, with some dominant traits some of the specimens can be visually identified as heterozygous or homozygous.

Codominant = Similar to “dominant mutant gene” except a Homozygous specimen can be distinguished from a heterozygous specimen 100% of the time.

Double heterozygous = Has two gene pairs where one gene in each pair is normal and the second gene is a mutant gene. I.e. double heterozygous for snow would have a normal gene paired with an albino gene and a normal gene paired with an anerythristic gene.

Triple heterozygous = same as double heterozygous except applies to three gene pairs.

Color mutations in boas:

Albino (AKA Amelanistic) - Two independent mutant genes: both recessive - a lack of melanin (black pigmentation) Kahl and Sharp strains.

Anerythristic - Two independent mutant genes; both recessive - a lack of red pigmentation. Two known strains (type I and type II)

Salmon (AKA Hypo) - Dominant - a reduction in the black pigmentation and often some increase in the yellow pigmentation.

Caramel Albino (AKA Tyrosinase positive albino) - believed to be at least two independent mutant genes; both recessive - has less than the normal amount of black pigmentation. Colombian and Nicaraguan strains

Caramel Hypo (Boawoman Hypo) - recessive - has leas than the normal amount of black pigmentation, similar to Colombian T-plus Albinos and Pastels.

Pastel (AKA Hypo) - Polygenic - A line of boas selectively bred for less than normal black pigment, not caused by a single mutant gene.

Blood - Recessive - A Hypererythristic mutation.

Named Color mutation combinations:

Ghost – homozygous anerythristic / heterozygous hypomelanistic
Super Ghost - homozygous anerythristic / homozygous hypomelanistic
Snow – homozygous anerythristic / homozygous albino
Sunglow – homozygous albino / heterozygous hypomelanistic
Super Sunglow - homozygous albino / homozygous hypomelanistic
Bloody Salmon – homozygous blood / heterozygous hypomelanistic
Moonglow – homozygous anerythristic / homozygous albino / heterozygous hypomelanistic
Super Moonglow – homozygous anerythristic / homozygous albino / homozygous hypomelanistic
Pewter - homozygous type II anerythristic / homozygous blood

Locale Related Color Mutations:

Sunset – homozygous hypomelanistic having 50% Hog Island Boa blood
Salmontine – heterozygous hypomelanistic having 50% Argentine Boa blood

Pattern Mutations:
Arabesque – Dominant? - A genetic circle-back boa with a ladder-tail, Typically highly speckled and often having a very brown color with some specimens tinted pink.
Jungle – Codominant - Originally identified in Sweden,
Motley – Codominant
Stripe – Recessive
Reverse Stripe – Recessive?
Leopard – Recessive - dark color, a mix of underlying tones and marbled pattern.
European Square tail - Recessive - long list of variable characteristics.
Scoria - Recessive? - Pink pattern-less with two parallel lines down back.
Aztec - Dominant?
Gray pattern-less - unknown

I know I use the word diverse for your collection but I might have to change it to distinct. It just sounds more appropriate and fitting. Got any brb's off feed yet or is it still too early and how is Mickey looking, like a stud or voyeur haha?
Bob

Thanks, I really have to admit, I myself drool when I enter the snake room. So much cool stuff to look at and enjoy.

Not really off feed yet, should be any week now although I have seen activity and am currently raising the temps slowly back to normal.

Mickey is probably too young and I may not get any litter at all from him and Molly. Ah well, worth the gamble to me. Molly is a wee sprite, barely old enough and barely large enough to breed. If she does take, it will be a small litter. Just what I want for the hets.

A little more to the Co-dominant and Dominant thing.

The following are Co-dominant mutations in Boas:
Jungle
Motley

The following are Dominant mutations in Boas:
Hypo/Salmon
Arabesque
Aztec (possible Co-dom)

Pastels are neither co-dominant or dominant. Pastels are derived from selective line breeding for a reduction in melanin, and sometimes an increase in color. Pastels are a form of hypomelanism, but their genetics isn't cut and dry. There is no mutation per say that causes the Pastel trait, however it is something that can be passed on. Here is where the term polygenic mutation comes into play. There are multiple factors that result in Pastels and by breeding select animals together you can get a higher likelyhood of secureing those traits in the offspring.

The difference between co-dominant and dominant mutations falls in the homozygous form. If the homozygous form is visually aka obviously phenotypically different from the heterozygous form the mutation is co-dominant.
When you see ads for co-dominant Hypos or possible dominant Hypos the terminology it incorrect. It should say Heterozygous Hypos or Homozygous Hypos. To make is simple, Hypo or Super Hypo. All Hypos are dominant, that is the type of mutation it is. An animal isn't co-dom or dom, a mutation is, an animal is heterozygous or homozygous.

In Co-dominant mutations like Motleys the Heterozygous form (Motley) is visually different from the Homozygous form (Super Motley, Patternless).

I hope this makes sense, I often have a tought time explaining it through text.

hey what about stripes and reverse stripes? are they just something that happens or can you breed for it?

There is a Stripe mutation that is recessive. Peter Kahl's Stripe boas.

There isn't a definite reverse stripe mutation, however some of the Jaguar boas that Frank Martin is working with produce some reverse stripes. This mutation is either dominant or co-dominant. A Super form has not been isolated yet, so right now it is Dominant. The same goes for Arabesques and Aztecs they may end up being Co-dominant mutations after all.

Stripes and reverse stripes also occur at random or are caused by environmental factors such as fluctuation in temperatures when a female is gravid.

Jungles, and Hypos can throw Striped and Reverse striped babies.
The Harlequin bloodline has done so as well.

Some abberencies are genetic, some are not. Includes stripes and reverse stripes. And those that are genetic, there is variable expression so some will be really striped while others have minimal stripes. Line breeding can get you to bigger and longer stripes.

This is a Brazilian rainbow boa I recnetly acquired with tons of striping, hoping it will be at least somewhat genetic and I can produce more.....
