If you breed a 50%het to a 50% het would the off spring that look normal also be 50% het?

You get 50% poss hets when you breed a het to a normal.

If you breed two 50%ers and there are no homo animals then it'd be pretty hard to tell if you have the genes to say if they are anything but normals. At best you could say they are 25%ers. If by chance you happen to get a homo snake then you would have 66%ers because you'll know that both the parrents carry the gene (100% het).

Im not sure what the percentage would be but in reality they are either hets or they arent. If you get some albinos in the clutch then they would be 66% het as both parents would prove to be 100% het. If you get all normals then you may have nothing or you may have hets. No way to know without breeding them out. Could be 66% with 2 het parents or could be 50% with 1 het parent or could be 0% with no het parent. Trouble is they all look the same. I hope I got all my stats right. Others will be more knowledgeable in this area than I am and can provide some better info.

Ok first of all are you sure what you mean by "50% het?" Do you just mean het or do you mean an animal with a 50% chance of being het? Because het by itself already means half/half.

If you just mean het x het then you get 50% hets, 25% normals, and 25% homs. The "normal looking" offspring would be 67% chance het.

If you mean 50% chance het x 50% chance het, then you could get just about anything from the above as a best possible chance to all normals as a worst possible chance.

I think I got that right...

-Imp

Het means that the animal is carrying 2 different genes. 50% het means that there is a 50/50 chance that the animal has the morph gene. 100% het means that there is a 100% chance that the animal is carrying that gene etc. Hope this helps.

and anyone who reads all these numbers is 50% certain to get a raging headache, unless they have bifocals then they are only 23% certain, but if their parents where 25% certain than they would only get 15% of the headache, i on the other hand have 2 100% headache parents therefore i recieved 155.9% of the headaches allowed on this forum.....i think i got all that right.......hhehehehehehe!!

p.s.- TASHA--how can you tell if a snake is homo?? i personally cant tell the difference between a str8 one and a homo one, nor did i know that snakes were able to be that way,........ ;-p

LOl - It's actually quite simple to tell the homos from the str8s. When your cleaning out cages and you've got two males that you've thrown in together while you're doing your cleaning, then you come back and find them hooked up. Well there you have it. Yes it does actually happen!

Here is an idea to test for Homo versus Str8:
Throw in a Gerbil. If the Gerbil goes in the front he is 100% Str8. If the Gerbil goes in the back he is not.

That is sooooo wrong. Funny...but wrong. =)

What else can I say other than whatever the outcome of the test I'll love them just the same...

Rob Reiding.

below is sort of correct....I have a headache.......

.........50 to 50 is either proven to be 100% each if they throw the homo morph or the babies will then be probably less than 25% chance of being het.if you get all normal looking....

which is why you never breed 50 to 50.....

get at least one 100% of some sex,.......(male...).and or a homo for a morph to prove or disprove the 50% 'ers.......

this is also why I am keeping very very few hets that are not 100% guarenteed to actually be het.......

.anyways..........I need an Excedrin........

..........and.......snakes are not gay.....they just don't care.......or they can smell a female on the other male???

.................

So what that really means in real terms is that when you think you have a 50% chance of getting a headache today, just put your bi focals on and reduce that chance by more than half to 23%. I don't usually wear bi focals, but this would be a good opportunity for me to start wearing them, hehe...

Rob Reiding.

When breeding 50% x 50% the resulting offspring may be Homozygous (visual morph) indicating that each parent animal is fully Heterozygous for the given trait.

However, if no homozygous offspring are present...who knows? The male parent may be Heterozygous and the female Normal, the female parent may be Heterozygous and the male Normal, both parent animals may be completely Normal, or both parent animals may be Heterozygous but the odds were against you in this clutch. You may never know which parent animal is Heterozygous...if either. And proving them Heterozygous or Normal could take several years.

This is why most recommend that at least one parent animal to be either Homozygous or Heterozygous. This way you only need to prove out a single parent animal...which takes a lot less time.
