Question

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).

Answer 1

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

Step-by-step 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%
