Hi,

A friend of mine is starting to have a little group of Cal King with different morph but he is wondering what are the genes types.

Could someone tell me how the morph work ?

I mean, wich gene is recessive, co-dom etc...

Or if there is a website or article that talk about this. I did a search on the web but found nothing.

thank You for your help !

Ok Cali Kings

the morphs avaliable are:

T- Albino (lack of black pigment... with pink eyes)

Lavender Albino (light and dark varieties... same gene different look , both have ruby red eyes not pink)

"Blue-eyed Blondes" i think it's a type of hypomelanism (hypo= reduced black)

and in recent times there's been discussion of an Axanthic (axanthic = lack of yellow pigment)

there are Ghost cali kings but i don't think it's a recessive trait.

Striping in cali kings is Co-dominant

how to morph work...

Snake Mutations are Homozygous

lets say you're breeding albino cali kings if you were to breed an albino to another albino that would be HomoZ to HomoZ which will produce all HomoZ (all albinos)

if you Breed an Albino (HomoZ) to a "normal" "wild type" you will produced animals that are 100% Heterozygous for albino (Heterozygous= normal looking but caries the trait)... when you breed 100% het back to each other 1 out of every four snakes will be HomoZ (albino)

now if you wanted to breed two different mutations together lets say lavender albino and T- albino ( both types of albino but the two genes are not compatible)

Albino X Lavender will give you all "normal" looking babies which are 100% Heterozygous for both albino and lavender... breed those hets back together and

Offspring are predicted to be...
4/16, Het for albino, Het for lavender
2/16, lavender, Het for albino
2/16, albino, Het for lavender
2/16, Het for lavender
2/16, Het for albino
1/16, albino-lavender (masked) double Homozygous (expressing both genes simultaneously)
1/16, lavender
1/16, albino
1/16, Normal

all albinos shoud be sold as possible het lavender
all lavenders shoud be sold as possible het albino
all "Normals" should be sold as possible het for albino and lavender

if you Breed a 2x Homozygous (albino-lavender)to:

an albino: you'd produce all albinos that are 100% het lavender

a lavender: you'd produce all Lavenders that are 100% het albino

an axanthic: you'd produce all normal looking animals that are 100% het for albino, lavender, and axanthic (i.e a triple Het.)

i hope all that makes sense

Ghost is recessive and proven.

Melanism (Mendota, Davis, Baja) are also recessive and proven.

Kerby...

Thank You

We already know how Genetics work, not first breeding.

So all the albinos are recessive like I tought.

The ghost is probably recessive to like it's have always been.

so the only special morph is the stripe witch is co-dom ? that mean there is a super-stripe form ? what does it look like ? or is because Stripe is dominant and not co-dom ?

Is there other morph that exist ? I think there is one that is all brown or something like that ?

sorry striping is Dominant... it's not a mutation

the chocolate cali kings aren't understood as yet (some think they are a cross) but i don't think it's a mutation

Not a mutation ?
what do you mean by this ?

And Thank You for everything else !
So everything is recessive, only stripe is dominant. What about motly I think it's a gene for cal king isn't it ?

The albino genes aren't on the same allele so they aren't match. Breeding an het albino with an het lav albino won't get you albinos.

Is there other morph that exist ? Or what are the designer morph ?
Some picture would help too I think.

Morph = Mutation
the striped kings are a found in he wild... if you bred a striped to a striped you'd get majority striped and some may be aberrant, or you may get a banded or two. the gene is dominant... if you bred striped to banded you'd get aberrant babies because both striping and banding are dominant...

Motley is a gene associated with Cornsnakes
Here's a Link to just about EVERY Cali king there is...

I believe the recessive genes have been mentioned.

There are a lot of names associated with cal kings to describe what they look like. BUT they aren't recessive and aren't always predictable. It is just a description only.

Thanx for the updated link... i was looking for it!

that Corn snake in your gallery... the one what doesn't have eyes... what happened to it?

Taking it to the Tucson Reptile Show this weekend. I'll be leaving in a few hours to head on down there.

Kerby...

so it's 100% healthy feeding and everything?

when did it hatch out... `04?

It is an '04, eats once a week. A very friendly and curious snake! Oh, and very pretty orange as well - just no eyes.

Kerby...

that's pretty cool... please post an updated pic of that snake when u have a chance

thanx for all the info

Thank You for the link.

>>I believe the recessive genes have been mentioned.

All those are
Albinos - recessive
Lavender - recessive
Banded - wild type dominant ?
Stripe - recessive
Ghost - recessive
Melanistic - recessive

>>There are a lot of names associated with cal kings to describe what they look like. BUT they aren't recessive and aren't always predictable. It is just a description only.

So they are genetics just that no one know what they are yet ? may be cause it's a variety of genes that make their look and not only one ?
like those

High Whites
Chocolate
Bananas
Blizzard
Spotted
Reverse Stripe

Thank You for your help !

love this world, don't hate it.

All those are
Albinos - recessive YES
Lavender - recessive YES
Banded - wild type dominant ? JUST A NORMAL
Stripe - recessive NO, IT IS NOT RECESSIVE
Ghost - recessive YES
Melanistic - recessive YES

like those

High Whites - NOT RECESSIVE
Chocolate - NOT RECESSIVE
Bananas - NOT RECESSIVE
Blizzard - YES, IT IS A COMBINATION OF 2 RECESSIVE GENES (albino & melanism)
Spotted - NOT RECESSIVE
Reverse Stripe - NOT RECESSIV

**So they are genetics just that no one know what they are yet ?**

The jury is still out on Chocolate Bananas. They came from double hets (albino & melanistics). They may just be a melanistic banana. I produced what appears to be 2 Albino Chocolate Bananas from breeding 2 double hets (albino & melanistic).

A lot of the "names" for cal kings are just aberrants (other than normal).

>>Morph = Mutation
>>the striped kings are a found in he wild.

It's still a mutation, it's just a wild mutation. Just like you could find albinos in the wild. It's just not a selective breeding or a designer morph then ?

>>Motley is a gene associated with Cornsnakes

I think people use "spotted" for the cal king ? so I am assuming it's a dominant gene just like the stripe is.

love this world, don't hate it.

In cornsnakes "motley" is a recessive gene. Spotted in cal kings is not recessive.

In cornsnakes "stripe" is recessive. Stripe in cal kings is not recessive.

Richard Zweifel had a paper in the Journal of Heredity in 1982. It has a good discussion of striped and some preliminary info about some other mutants.

Bern Bechtel had a piece about albino, but I do not remember where it was printed.

I call black and white with a banded pattern wild type. It is also called desert phase.

Coastal phase is brown and pale yellow with a banded pattern. I do not know whether that is a single mutant or not.

Striped is a dominant mutant gene with variable expression.

There are probably several independent mutants that affect pattern in addition to the striped mutant. Zweifel had a couple but hadn't worked out the inheritance. The 50-50 black and white banding may be one, and I've seen pictures of kings with very narrow white bands. Wide striped may be a combination of striped and whatever produces 50-50 banding. I have no clue to inheritance of any of them.

It would not surprise me if many of the mutants had several different names in the trade.

A friend of mine mated a wild type with a poorly striped Cal king that had normal coloration. Among the babies were an albino and a baby with pink eyes and skin that was about two thirds as dark as normal. Probably two different mutant genes, both recessive to their normal counterparts.

I am not aware of a web site with an organized list of Cal king mutants, but I haven't looked hard, either. Someday ....
