Assuming independent assortment for all gene pairs, what is the probability that a cross between the following parents, AABbCc × AaBbCc, will produce an AaBbCc offspring?

Question

For each gene pair (A/a, B/b, C/c), the probability of the offspring inheriting the desired alleles from both parents (i.e. Aa, Bb, Cc) is 1/2. Since there are three gene pairs, the probability of all three occurring together is (1/2) x (1/2) x (1/2) = 1/8.
