Ok so i bred a motley 100 % het. Albino to what i thought was just a hypo. She gave birth to a whole mix of things including sunglows and albino. So hypo ended up being a het. Albino Now being the hypo carried the albino gene and proved out would that make her 100%het for albino? And will the normals in the bunch be 100% het for albino?
If you breed a Het to a Het, the non-albinos will be 66% Het Albino.
I though 66% het. Was if you breed a 100%het to a normal then the babies would be 66%? This were i may be wrong. Doesnt hurt to ask. I dont know everthing. But sure as hell trying.
A percentage for hets is simply how likely the animal is to carry that recessive gene. If an animal is 100% het for albino, it definitely carries one copy of the albino recessive. As soon as animal produces a visible recessive, whatever percentage it had, it is now 100%, because it has been proven it definitely carries that gene.
Any offspring of a visible recessive who are not visible will be 100% het for that gene.
Any offspring of a 100% het to a normal with no het will have a 50% chance of carrying the gene, and 50% chance it doesn’t, and there’s no way to know without proving it out via breeding, so it will be a 50% poss het.
Offspring of two 100% hets have three possibilities. They could have inherited the carried gene from the mom, they could have gotten it from the dad, or they could have failed to get it from either. The chance they do have this gene is roughly 66%, so they will be listed as 66% het til proven.
I hope this helped explain the terms and what’s going on, I worry I tend to ramble a bit…
It’s good to ask questions when you don’t understand. Can be annoying when you find yourself enjoying critters, and suddenly it’s math.
Ok now that was said perfect. Completely under stand Now. thanks for the information . Talk about a suprise. Thought i was only going to get some hypos and some motleys. THANKS AGAIN BUD.
Glad you got that sorted. Nice explanation, @citricprincess.
Back in the day, the usual way to refer to possible hets and the percentage of their occurring in each animal was with a “% ph,” for “% possibly het.” It does make more sense to say “50% ph” than “50% het.” I know the latter is the way it usually appears now, but it’s confusing to new people until someone explain it.
It’s not possible for an animal to be partially het for any trait. It’s het or not het, and the percentage is for the probability. And…
This is a very logical conclusion - but it only works for fractions. These percentages are probabilities, not fractions.
Me too. Rambler. Couldn’t have put that better!
@citricprincess Citrus. Thank you for the explanation! I am not a breeder but sometimes it’s nice to be able to understand what you breeders are talking about!
