Black hair in rabbits is determined by a dominant allele, B. White hair results when a rabbit is homozygous for the recessive allele, b. Two heterozygote rabbits mate and produce a litter of three offspring. a. What is the probability that the offspring are born in the order white-black-white

The answer if 3/64 or 4.69%

Explanation:

B-: Black; bb: white

Two heterozygote rabbits: 2^2 = 4 possible gametes.

P: Bb x Bb F1: 1/4 BB; 2/4 Bb; 1/4 bb there are 3/4 black and 1/4 white

The probability that their offspring are given birth following the order white - black - white is:

1/4 white * 3/4 black * 1/4 white = 3/64 = 4.6875%
