II. SOLVE THE GIVEN PROBLEM 21-25. In fruit flies, humans and other mammals, sex is determined by an X-Y system. However, many organisms do not have the X-Y system of sex determination. For example, birds have a Z-W system. Male birds are zZ, whereas females are ZW. In chickens, barred feathers (Z®) are dominant over nonbarred feathers (Z*). a. Draw a Punnett square that shows the results of a cross between a barred female and a nonbarred male. b. What is the probability of the offspring will be: a. Barred female? b. Nonbarred female? c. Barred males? d. Nonbarred male?
