Answer:
Here is the full question:
Each of two parents has the genotype blond divided by red, 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 red divided by red genotype?
c. What is the probability that the child will have blond hair color?
Explanation:
a.) Remember that the pair of allele determines the hair color. So, each of the two parents have the genotype red/blond. Therefore, the possible outcomes are blond/blond, blond/red, red/blond, and red/red.
b.) Since there are four outcomes, We calculate this as P(red/red) = (1/1)/(1/4) = 0.25
c.) There are three outcomes of the child having a blond hair which are blond/blond, blond/red, and red/blond. The probability is therefore P(outcome of blond/total outcome) = 3/4 =0.75
