Brown eyes (B) are dominant to blue eyes (b), and the allele for freckles is recessive. What is the probability that the couple below will have a son with blue eyes and freckles?

The question is incomplete. The complete question is:

Brown eyes (B) are dominant to blue eyes (b), and the allele for freckles is recessive. What is the probability that the couple below will have a son with blue eyes and frecles?

Mom has blue eyes and freckles

Dad is heterozygous for both eye color and freckles gene.

According to the question, Mom has blue eyes and freckles, which means she is bbff. The Dad is heterozygous, so BbFf. Crossing their genes, we have:

BbFf x bbff

            bf

BF      BbFf

Bf       BBff

bF      bbFf

bf       bbff

So, as both freckles and blue eyes are recessive, the only possibility for the son to be both is bbff. For that, the probability is 1:4 or 25%.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
