Hmmmmm...

We continue to work with our PE Stripe line, and we hatched out a very interesting female this year.

It looks a lot like a TSK Tri Stripe.

Mostly we see partial and full stripes from this line. We have crossed the PE Stripe into Lessers, Pins, and Ghosts, and seen the striping pull through as well, both full and partial.

I would say this PE "Tri" Stripe female was a lucky oddball, inconsistent with the rest of the PE Stripes, except that we hatched this male in 2008 from this same line...

I know there are inheritable genetics in the PE Stripe line, I just don't know how to describe it. Sometimes it is dominant (or co?) and sometimes it acts recessive (as with our normal looking DH Ghost PE Stripes, that look normal, but throw PE Stripe Ghosts). Continues to puzzle. But in a good way...

Very cool!

I would venture to guess that it is polygenics- multiple genes influencing the same trait, and the degree of expression of the trait depends on how many of the genes are expressed. Like skin color in humans. The more dark ones you inherit the darker the skin tone, the more lighter ones you inherit the lighter the tone, inherit equal number of dark and light genes means medium tone....and every shade inbetween.

I think this is what is happening with pieds. Any pied can throw any degree of white offspring. BUT higher chances of getting high whites from two high white parents and low whites from two low white parents and all permutations in between.

Someone else on the forums had what appeared to be a "het" tristripe a while back. Don't remember who it was. TSK's seems to behave as simple genetics, but it may be that their stock is carrying a lot of genes for that trait, resulting in a fuller stripe all of the time when het is bred to homozygous. But homozygous to normal passes on only some of the genes, so the "hets" have some visual "markers" that may really just be very low expression of the trait.

Just my two cents. It seems like many of the traits we see in balls are governed by simple mendelian genetics, but I think there are a few examples of incomplete dominance, polygenics, etc lingering around! Really, really cool stuff!

Very well explained.

Thanks.

Thanks! I'm not saying that is what's happening, but it does make some sense. Clearly lots of genetics tests would be needed to confirm. BUT there are lots of possibilities to explain some of these fantastic results that we see in these animals and I think it is pretty amazing!

Look at the Blue Eyed Leucistic complex. Great stuff. Multiple Allele systems and all.

Hey Robyn, nice snakes! To me, it sounds like a co-doom with a "weak" het phenotype...other mutations may mask it in the het form, but not the super.

Look at pied markers for example....they don't tend to show up on stuff with really clear bellies like lessors, etc. Even TSK's het tri-stripe looks pretty obvious (of the few I've seen), but I bet it wouldn't be on something with a reduced yellow pattern (mojave, lesser, etc).
