Patt. or Blizzard?

thegeckobarn Feb 10, 2004 02:43 PM

I purchased him and his brother as patternless..but ive had a few ppl say he looks blizzard. So im not 100% sure anymore.
Anyone got any ideas?

The link said since i wasn't a member i couldn't view.

I am pretty sure it is just my browser. What is your browser? (netscape, internet explorer, etc) Mine is netscape and lots of times images just dont load. Don't feel bad.

I couldn't be of any help sorry, but it is a beautiful gecko. The only difference between my blizzard female and my patternless female is that Lily, the patternless, has a hint of yellow to her whereas Nala doesn't. I always wondered how you'd tell a patternless from a banana blizzard

Looks patternless to me, but I don't have much experience...

And for future reference, your webhost for your site doesn't allow image remote linking...

Thank you!! My partner will get rsome close up shots of his head tonight, for further identification.

But if he truly is a patternless, thats GREAT. I bred him with my 66% het PA female, and she is now gravid, and I hope to produce some patternless and albino babies from them!!

Thanks again!

Definately patternless. 100% sure. No if's, and's, or but's. Lol. A blizzard is white through-and-through. With a tint of yellow. But that is way to much yellow, I think, to be considered a blizzard. Also, the orange at the base of the tail is a thing that most patternless have. I haven't seen one blizzard with that, although I could be wrong.

Hope that helps,

GREAT! Thank you, I was hoping hes a patternless if he was bred to my het female. AWESOME!

OKAY So, what happens if you bred a Patternless to a Blizzard? Surely the babies would not be normal, right? After all, they don't have the genes for it - both parents would have 2 recessive genes of their morph.

So what would the babies be??

~~Dusty

thegeckobarn Feb 10, 2004 07:43 PM

actually...I believe there have been morphs such as these produce normal babies. Such as albino's producing normal het babies. As far as ive been told.
I obviously dont know how this works, but im assuming they would produce patternless het blizzard and blizzard het patternless babies? 50% hets?

Dunno

geckogod2 Feb 10, 2004 07:53 PM

one is blizzrd, one is patternless.. all the offspring would have half of each others' genes resulting in a normal looking offspring that is double het. for blizzard and patternless

think of one gene as having two parts.. when you breed, the male gives up half its genetic code, the female gives up half its genetic code. then the those half genes are combined back together.

hope i didn't confuse anyone further..

thegeckobarn Feb 10, 2004 08:00 PM

ahhh, so THATS how you get a double het, cool stuff..hehe. As I have a few double hets myself, and wasnt sure about how they are classified as such.
Neat to know *thumbs up*

I still don't get where the Normal gene comes from, though. If either parent had the Normal gene (the dominant gene), it would show through, right? But to be a patternless, you have to have both recessive genes. So where does the Normal gene come from in the kids? How can they have that trait when neither parent possesses it?

The genes are not on the same chromosome.

Just like albino is not on the same chromosome as patternless, and its possible to get double hets and double homozygous for both traits as well as combinations of het and homozygous.

ok..quickie genetic lesson..

we will use "R" to represent the dominant normal gene for blizzard
we will use "T" to represent the dominant normal gene for patternless
we will use "r" to respresent the recessive gene for blizzard
we will use "t" to represent the recessive gene for patternless

Each gene has two active parts to its make up.

the blizzard has two recessive genes for blizzard (noted rr)
the patternless has two recessive genes for patternless (noted tt)

the genotype for the blizzard would look like this rrTT . the rerason for this is beacuse the blizzard gene is expressed and has no patternless genes that we know of, so the place where the patternless genes would exist is taken up by two normal domainat genes (noted TT)

The genotype for the patternless would look like this RRtt . The reason for this is because the patternless gene is expressed and has no blizzard genes that we know of, so the place where the blizzard genes would exist is taken up by two domainat genes. (noted RR)

Assuming the male is blizzard and the female is patternless each gecko gives up half his genetic code.

For the male which is blizzard(noted as rrTT), he gives up half its genetic code (being one "r" and one "T"
For the female which is patternless (noted as RRtt), she gives up half of her genetic code (being one "R" and one "t"

so now we have the following genes: "R" "t" "r" "T"

now we pair them together (remember sperm and egg joining from science class)giving us a combination of "RrTt"

now it takes two recessive genes (lowercase letters) to express a certain abnormality or recessive trait. this is called homozygous. If two are not present, then the recessive gene cannot be displayed and the dominant normal gene is displayed. when there is one normal domiant gene and one recessive gene, this is referred to as heterozygous, meaning that the individual carries the rescessive gene but does not display it..

your end result is a gecko with a genotype of "RrTt" meaning it carries the genes for blizzard and patternless but it cannot display them..

since it cannot dispaly them , they take the appearance of a normal gecko but are heterzygous for the genes or patternless and blizzard.

For clarity, genotype is the expression of genes using letters, phenotype is how the animal looks on the outside.

i hope this helps.. email me with any questions... also feel free to copy and paste this for other forums and/or yourself , but please don't copy this info for your website..write your own..

OK Gotcha ... That's what I wanted to know.. Thank you!

StinaUIUC Feb 10, 2004 09:57 PM

Technically the way GeckoGod described it isn't really the best...that's not really the way it works...

The normal pattern and coloration is a sort of default...it is controlled by multiple genes, and when no other gene is affecting it, the animal appears normal. Recessive genes normally cause some sort of innactive protein that doesn't allow the normal pattern or colors to show. For example albino is recessive, when an animal is homozygous recessive for the albino gene it causes disfunctional proteins that are needed to create pigment...thus the pigment is not produced and an albino is born! lol I'm not sure exactly the way blizzard and patternless work, but I'm sure it is something similar, the change in DNA sequence causes a disfunctional protein of some sort that messes with the animals appearance; however if the animal is heterozygous or homozygous dominant, then it can still produce functional proteins, and therefore will have normal color and pattern. In the case of a heterozygote, the animal will produce functional proteins from only half of its chromosomes because the other half produce the disfunctional ones...however the half is usually enough to still produce a normal appearance; this is also why sometimes hets will have a different appearance from homozygotes.

my method the way i explained is fine, if not then the whole idea of punnets squares is wrong as well and that is what most ppl rely on when doing SIMPLE genetics..i have no doubt what you said goes on at the molecular level...but try and explain a triple trait cross (snow striped corn)that way and you'll be putting ppl to sleep as well as have them scratching their heads. Call my method sugar coating it or whatever... its simplified enough that ppl can understand some genetics and that you don't need to be a genetic engineer to understand basic genes. Ppl are confused enough about genetics already, if they weren't they would not have asked for help.

geckogod2

StinaUIUC Feb 10, 2004 11:31 PM

lol...its just that the way you explained it made it sound as if the dominant genes from both traits produce the same effect...which is just wrong. It would be more accurate to say that the recessive traits "hide" the normal color and pattern. When the animal has a dominant allele the normal color and pattern is not affected...but having the recessive genotype gives the animal a different appearance...it's not ridiculously complicated...this is stuff I learned in freshman year college bio class, and maybe before that...I'm only a sophomore now and I am in a genetics class...but all we've done so far is really punnett squares. What I explained does not change the fact that punnett squares work...I just explained why the recessive trait changes the appearance of an animal. Punnett squares just tell you the genotypes of animals, then you can take the genotypes and find the phenotypes...why would how expression works change the way a punnett square works? Anyway, I'm kind of ranting...I just don't feel the way you explained it is correct. If you want "sugar coating" then say that the recessive traits hide the normal appearance, but when bred with a normal animal, or an animal with a different recessive trait, the normal appearance will come back in the offspring because the recessive trait is not homozygous to hide it.

Wouldn't it be erroneous to say that an animal that is homozygous for a recessive trait is having its normal appearance masked? There is no genetic potential for a normal appearance in such animal.

If anything its the reverse, the dominant normal gene masks the potential of the recessive gene that is heterozygous and lying dormant.

StinaUIUC Feb 11, 2004 01:14 AM

oh also...there is no one dominant normal gene...a normal appearance is created by the interaction of many different genes...its just that its very easy to change the appearance when an animal is homozygous recessive. As I was saying, recessive alleles cause a change in the DNA sequence, which leads to deffective proteins, which ultimately changes the appearance of the animal. In other words...if an animal is dominant or heterozygous (assuming simple complete dominance) for all genes affecting appearance...it will appear normal...but if it is homozygous recessive for any trait affecting appearance it will not look normal because something is not being produced to exhibit a normal pattern or color; however if an animal that is homozygous recessive is bred with an animal that is homozygous dominant, the offspring will appear normal because they aren't homozygous recessive and can produce whatever is needed to exhibit normal pattern or color. That's the simplest way I can think of to put it correctly...

...also I think that some recessive traits affecting appearance can cause the production of something extra, instead of not producing something.

willingness to admit fault is one of the greatest traits a person can have Genetics can be very confusing, and if you don't have an interest in it it makes it even more difficult to understand. Personally I find genetics very interesting, and I like to know why things work the way they do. Hence the reason I'm in a genetics class! (well...besides the fact that its required...lol...I'd have taken it anyway though)
