Two leaf types, at (F) and curled (f) are recognized in camas (Camassia quamash) with at being dominant. Two ower colours also are noted, blue (B) and white (b), with blue being dominant. If one parent is double-heterozygous, FfBb and the other is double homozygous recessive, bb, what is the probability that an ospring from these parents will have curled leaves and white owers?

the final answer is 0.25

i draw the tree diagram but i got 3/8 not 2/8
