Answer 2

C. Pink and white will yield 1 pink: 1white in the offspring. 1/2 of the offspring should be white. That's the highest ratio of white in the problem. (Do RW x WW)

Pink = RW Red = RR White = WW
C. RW x WW

A. Pink and pink will yield 1 red: 2 pink: 1 white. - only 1/4 of the offspring would be white. (Do RW x RW.)

B. Red and white will yield all pink, no white. (Do RR x WW)
