So I got this email this morning telling me that an albino(visual) x normal does not produce 100% hets. My response was not what i wanted it to have been but its 7:09am.

Oh, shoot!!! Now I have to rethink almost all of my breeding plans!!!!

Well, that is news to me...

Interesting. I must go back to my genetics 101 college textbooks and reread some things.

Balls for Life, Baby!

Please post the reasoning given for why the babies would not be 100% hets. I think there is a flaw somewhere in the reasoning. Or else I am misinterpreting the breeding problem. For what it's worth, the Genetics Wizard says that homozygous albino x wild type --> 100% het albino.

Theoretically, there is no such thing as 100% het. A visual albino (homozygous) to a normal WILL produce het (hetrozygous) albino young. All other possibilities are described as 66% poss. or 50% poss. hets. Which means that the offspring have a percentage possibility of carrying the albino gene.

>Theoretically, there is no such thing as 100% het.

The way the original poster used "100% het", I wasn't sure whether it meant that 100% of the babies were heterozygous or whether there was a 100% probability that the babies were heterozygous. I would certainly agree that "100% probability heterozygous " is just a long way of writing "heterozygous".

I'm happy to say that so far I haven't seen "albino x normal --> 100% 100% probability het albino".
