Has anyone proved less than 100% Hets.?

[artist&writer]

Has anyone been able to prove out recessive traits in BP's that are less than 100%?
Like 66% PH's., and 50% PH's?

50% possible het means that you have a 50% chance of proving it out. (The snake has a 50% chance of carrying the gene.)

66% possible het means that you have a 66% chance of proving it out. (The snake has a 66% chance of carrying the gene.)

So, I would imagine that people are successful proving out 50% and 66% possible hets about 50% and 66% of the time, respectively. I know that there are quite a few folks on this board who have done so ... I have a whole little army of possible hets that I'm hoping to try and prove out in the coming years. (I'm gonna be real stoked if even 50% of them prove!)

In theory, you can increase your chances of proving one out by looking for possible hets with "marker traits," alterations in the pattern of the animal that suggest the influence of a heterozygous recessive gene behind the scenes. This is especially well-known in het pieds, in which the pied gene seems to "break through" on occasion even if only heterozygous. (Not producing a pied pattern, but "funking up" the pattern a bit.)

I'm working on proving out a pastel butter 66% hypo.

I know Randy Remington has proved out a couple 25% het pairs.

Beat me to it. Just to point out as well, in your proving out of a possible het, you could also end up with bad luck and not produce any visual recessive morhps, leaving you to wonder if you just had bad odds or its not a het. Then you are left to wonder how many more times do I try to prove this animal out.

This is why I try to stay away from Possibles. Key word try.

Last year, a hobby breeder I know in the Hampton Roads, Virginia area bred 50% Het for Albino BPs that she purchased from two seperate sources, 18 months apart. She produced 0.1 Albino out of 5 eggs. I told her she needed to head straight for Vegas...

When you do prove out a 50% or 66% Poss Het...that moves it into the 100% Het category, right?

Wow, did she play Mega Millions a few weeks back?

Yes, a proven poss het "becomes" 100% het at that time.

Apparently most of the currently-existing lavender snows came from possible double het parents:

Lavender snows!

Additionally, if you have a 25% poss het, and its 50% poss het parent is proven het, then yours becomes 50% poss het.

(I try to use 'poss het' because saying '50% het' seems to create a lot of confusion for newbies).

Once an animal is proven to carry a gene, that's it. It's a het.

It either is, or is not, het for that trait. The percentages are just percentages of the odds that it will carry the gene. So, a 100% het is guaranteed to be a het--there is no chance that it isn't a het.

I'm looking forward to seeing a simple scale test or blood test that will reveal het status in ball pythons. Someone is bound to offer this in the future. Getting DNA tests done on cattle is cheap, so why not ball pythons?

Lavender snows!

I KNOW RIGHT?

But I haven't seen any recently-updated pictures of the original lavender snow, and man, would I like to! Since lavenders usually color up as they age...
