ok, planning on buying some triple hets so i went to genetics wizard to see what is the probability of producing the "visual triple het", either whiteside snow or white side ghost. the probability of getting that morph is 1 out of 64. adding up the percent of offspring phenotypes from a pair of triple hets say for ws snow i could expect:

42% wild type- looks normal, but most are het or double het or triple het for various traits. the greatest eyebrow raiser, that is a lot of normal looking offspring.
14.1% albino- some normal and some het or double het for each trait.
14.1% axanthic- same as the albino, some normal some het or double het.
14.1% white side- same scenario as the other two recessive traits.
4.7% white side albino- some het for axanthic, some not.
4.7% white side axanthic- some het for albino, some not.
4.7% snow- some het for white side, some not.
1.6% the holy grail, white sided snow.

(i rounded the percentages so they probably do not add up to 100% exactly.)
well, someone is going to get lucky or we'll have to wait a couple of years before there is a white sided snow. it will be interesting to see how long it takes the trait to develop, and will probably be a good project for a longgg time.
how many other species have triple homozygous (visual) morphs- corns? bulls? hondurans? are any pythons or boas in triple het "mode" yet?

I know of some triple het rat snakes. I had a pair of triple het Texas Rat Snakes earlier in the year. Het for albino, leucistic and leucistic albino.

If your rat snakes are het for leucistic and albino, that would be double het not triple. There are two traits involved not three, LOL.

Keeping this on topic, there are quite a few triple morph corns out there. Stuff like snow motleys, snow stripes, ghost motleys, ghost stripes, etc. And like Mr. Kenderdine said there are probably four morph combos out there! I don't keep up with corns myself anymore now that there are so many hybrids and crosses mixed in.

They are het for all 3 traits. The leucistic albino trait only appears if you breed 2 double hets for albino and leucistic together.

There are only two traits involved, leucistic and albino. The "leucistic albino" is a combination of the two. There aren't three traits in your example. Maybe you are thinking in terms of phenotypes instead of traits? There are three phenotypes, albino, leucistic, and albino leucistic (along with wild type of course). Maybe that's where you are getting confused?

kk

There are only two (2) recessive genes involved with your example, not three.

Just like in corn snakes, combining two (2) recessive genes (amel & anery) DOES MAKE A THIRD RECESSIVE GENE. A corn snake that displays these two(2) recessive genes (amel & anery) is called a Snow corn, but corn snakes CAN NEVER BE HET FOR SNOW, the correct statement is that they are double hets(amel & anery).

In cal kings I bred a Blizzard (albino & melanistic) to an albino High White a couple of years ago. I produced ALL albinos that are 100% het for melanism. Still only two (2) genes involved.

Still confused?

No see, I knew what I was talking about. I just said it wrong.

... I'm still trying for any 2x visual stuff. I guess I'll let you guys do all the hard work and then take all the leftovers...
I believe there may be 4x het corns but don't know for sure or that if all the traits are visual??
There's so damn many (corn)traits nowadays I can't keep up.
Good luck with the projects.
:Mark

And lots of double het combos.

This year I bred a Lavender to a Blizzard (albino & melanistic) so all the babies will be 100% triple hets (Lavender, Albino, Melanistic). So in a couple of years I will be breeding them back to each other to produce a California Kingsnake that will display all three at the same time (hopefully LOL).

I already have double hets that are:
Lavender x Albino
Melanistic x Albino
Ghost x Albino

I will have this year:
Lavender x Melanistic
Lavender x Ghost
Lavender x Albinos (more of them)
Ghost x Albino (more of them)
Ghost x Melanistic

Lots of projects for the next couple of years

Now, if I can just get ahold of some Blue-Eyed Blondes......

Kerby...

I wish I could help you in the blue eyed blonde category, but I only got infertile eggs this year.....I hate first year breeders....Maybe next year...
John Lassiter

That happens to me every now and then (once last year). Infertile eggs on first time breeders. The good news is that that same pair made all good eggs this year!

>>how many other species have triple homozygous (visual) morphs- corns? bulls? hondurans? are any pythons or boas in triple het "mode" yet?
>>db

In hondurans there are observable double homozygous (snows, and ghosts) and in likelihood a number of double-homozygous hybinos (hypo & albino) have been produced but they can't be distinguished from the albinos that aren't hypo. But no definite triple-homozygous yet, though that might have happened too--the babies that look like snows and that come from triple hets COULD be triple-homoz, but until they're test bred one can't be sure, and the odds are against it 4:1.

I've got a couple pairings this year that could prdouce DEFINITE double-homozygous hybinos (hypo het/albino x hypo/albino = babies 1/4 of which--the ones that look ablino--ARE hybinos, because all the babies are hypos).

And i've got one or two pairings that could produce triple-homozygous Hondos at a 1 in 16 rate (hypo het/albino het/anery x hypo het/albino poss het anery, so depends on whether the second animal really is het anery). The triple homozygous hondo would presumably look like a snow, but it'll be interesting to see.

LOL

I'm confused! LOL

At least you are keeping accurate records to keep all of the genetics straight in your Hondos.

I'm doing the same for my cal kings as soon I should be the first to produce some cal iings that display double, triple and quad recessive genes at the same time. Next year when I breed my double hets (lavender & albino) together will I be able to tell the difference from the 1/16 that displays both? Hope so.

Love your pics BTW
