How do you know which Hets are what?

[Clint Bundy]

When you breed and get hets I know you can put 33 or 60% on what they can possibly be. Are there markers on some hets to know for sure that they are 100%het or is it just a guess? I am looking to breed next year and this has been a question that I have always had. Thanks in advance.

You can have a 50%, 66% or 100% het! Some say het pied have markers but there is het pieds with no markers so the markers don't really mean anything. You need to buy hets from a well known breeder because there is no way of knowning what is het and what is just a normal. You need to breed to hets to known if they are hets or not! A het to a normal produces 50% possible hets which mean half the offspring is het but you can't tell so its a gamble. A het to a het produces 66% posssible hets and homozygous X normal(or het) will produce a 100% het!

"A het to a het produces 66% posssible hets "

so if u bred a het pied to a het pied u would get all normals 66% het pied, or would u get pieds??

"A het to a het produces 66% posssible hets "

so if u bred a het pied to a het pied u would get all normals 66% het pied, or would u get pieds??

When you breed 100% het x 100% het each egg has a chance to be a visual morph.Although sometimes you just miss the odds.So everyone will be a 66% het until proving out

With 100% het pied to 100% het pied - let's say a clutch is 4 eggs.

Each EGG has a 25% chance of hatching a pied (the animal received a pied gene from each parent)
Each EGG has a 25% chance of hatching a normal (the animal received the normal gene from each parent)
Each EGG has a 50% chance of hatching a het (the animal received a normal gene from one parent and a pied gene from the other parent).

So - let's say that this 4 egg clutch hatches statistically accurate and there is 1 visible pied and 1 normal and 2 hets.

You cannot visually tell the hets from the normal. So - 1 normal plus 2 hets is three wild type babies.

2 out of 3 are 100% het, or 66% of the three. So - all THREE of the normal type have a 66% chance of being the 100% het carrier. That's why normal appearing babies from 100% het to 100% het breedings are called 66% possible hets.

Does that make sense?

wow - this is the best explanation i've seen
i'm not sure if giving you more rep is necessary so i'm just thanking you LOL.

Breeding two of the same visual recessives together will give you all visuals.
Breeding two different recessives together will give you double 100% hets. (100% het. for each trait. Then breeding those hets. together, you could produce a double visual recessive, such as the albino piebald.
Breeding a visual recessive to a normal will give you 100% hets.
Breeding two 100% hets. will give you a possibility of a visual, and the others are all 66% hets. until proven out.
Breeding a het. to a normal will give you all 50% hets.

Hope that helps!

I guess I was wondering how some people will put 100% het on their snakes. This is now easier to understand. I only have 2 hets in my collection due to the fact I got them from a very reputable breeder with a guarentee on them being 100% het for Albino. I have decided to breed 100% visuals on anything I want to make next year. So other than the suprise of Ivory's and BEL's that I might have, I should be very happy. Then the mixing will begin next breeding season. Setting up Punnit squares was a very informative way of looking at things also. Thanks for your info so far too.

Your 100% hets were produced by breeding a visible Albino to another animal (normal, or a co-dom, etc). All the babies would be 100% het, because the Albino carries two copies of the Albino gene and passes one copy to all its offspring. So 100% off the offspring carry one copy of the Albino gene.
