The genes for eye color in a certain male fruit y are (R, W). The genes for eye color in the mating female fruit fly are (R, W). Their offspring receive one gene 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 be the number of offspring having red eyes and let Y equal the number of red-eyed offspring having (R, W) or (W, R) genes. (a) If the total number of offspring is n = 400, how is X distributed?

(b) Give the values of E ( X ) and 2 X = V ( X ).

(d) Give the values of E ( Y l ( X = 300)) and V ( Y l( X = 300))
