Among black Americans, the frequency of sickle cell anemia is about .0025. What is the frequency of heterozygotes? When one black American marries another, what is the probability that both will be heterozygotes? If both are heterozygotes, what is the probability that one of their children will have sickle cell anemia?
I've already solved the first two questions, and now I'm just focusing on the last question. My question is, would the probability of one of their children having sickle cell anemia be the original .0025 that was given to me? Or would it be .25 (the probability of two recessive alleles when you cross two heterozygotes)?
Thanks, in advance. =]
