Hello Gentlemen, Here's a statistical question for you: A man and a woman mate to produce a child that either has blue eyes (B) or green eyes (b), where blue eyes are dominant to green eyes. As you remember from biology, there are 3 different possibilities for the genotype - BB, Bb, or bb. The probabilities are 1:2:1 for BB:Bb:bb. Thus, the chance for the child to have blue eyes is 3/4 and green eyes is 1/4. Ok, I'm getting to the question now. The couple decides to have 2 children. What is the probability that the 2 children will have the same appearance and be of the same sex? Here's what I think the answer is: green eyes: (0.5*0.5*0.25*0.25)*100% = 1.5% blue eyes: (0.5*0.5*0.75*0.75)*100% = 14.1% Is this correct? Thanks.
