Question

Each of two parents has the genotype blond/brown, which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child. Assume that if the child has at least one blond allele, that color will dominate and the child's hair color will be blond. a. List the different possible outcomes. Assume that these outcomes are equally likely. b. What is the probability that a child of these parents will have the brown/brown genotype? c. What is the probability that the child will have blond hair color? a. List the possible outcomes. A. blond/blond, blond/brown, and brown/brown B. blond/blond and brown/brown C. blond/blond, blond brown, brown/blond, and brown/brown D. blond/brown and brown/blond b. The probability that a child of these parents will have the brown/brown genotype is ____ (Round to two decimal places as needed.) c. The probability that the child will have blond hair color is ____. (Round to two decimal places as needed.)

Explanation / Answer

a. A. Blond/blond, blond/brown, and brown/brown

b. P(brown/brown genotype) = (1/2)x(1/2) = 1/4

c. P(blond hair) = 1 -1/4 = 3/4

[when its not brown/brown, the hair color will be blond]
