• Question: I had a question in a science class once that said a small community had a recessive lethal gene that has been in the community for generations. A woman then has offspring that, while she herself does not have the disease, the offspring do. And then it asked "Which woman would it be" or something like that, and the answer was the heterozygous woman. What would be a good way to figure that out besides a Punnett Square?
