What is the probability that both parents will contribute a recessive allele for any given trait? Use the product rule to determine the probability of inheriting the recessive genotype (aa).

The probability of inheriting the recessive trait from both parents is 25%

Explanation:

According to the product rule when two alleles independently assort the probability of them occurring together is calculated by each of the probability.

In this case:

Since each allele is a 1/2 chance of 50% probability to be in inherited from either parent is 1/2*1/2=1/4 or 25%

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
