The genes for eye color for a certain male fruit fly are (R,W). The genes for eye color for the mating female fruit fly are (R,W).Their offspring receive one for eye color from each parent. If an offspring ends up with either (R,R), (R,W),or (W,R), its eyes will look red. Let X equal the number of offspring having red eyes. Let Y equal the number of red-eyed offspring having (R,W) or (W,R) genes. a.) If the total number of offsprings is n = 400 how is X distributed b.) Give the values of E(x) and Var(X) c.) Given that X=300, how is Y distributed d.) Give the values of E (Y|X=300) and Var(Y|X=300). Solution (a) X is b(400; 0:75); (b) E(X) = 300; Var(X) = 75; (c) b(300; 2/3); (d) E(Y ) = 200; Var(Y ) = 200/3 Daljit!.
