5. The probability that a child of these parents will have the blond / blond genotype is
Round to two decimal places as needed.)

Answer 1

The probability that the child will have red hair color is 0.75.

Thus, the probability that a child of these parents will have the blond / blond genotype is 0.25.

Explanation:

It is provided that each parent has the genotype red / blond which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child.

The possible outcomes for the hair color of the child are:

S = {R/R, R B, B/R and B/B}

There are four possible outcomes.

Compute the probability that the child will have red hair color as follows:

Thus, the probability that the child will have red hair color is 0.75.

Compute the probability that a child of these parents will have the blond / blond genotype as follows:

Thus, the probability that a child of these parents will have the blond / blond genotype is 0.25.

Answer 2

The probability that the child will have red hair color is 0.75.

Thus, the probability that a child of these parents will have the blond / blond genotype is 0.25.

Step-by-step explanation:

It is provided that each parent has the genotype red / blond which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child.

The possible outcomes for the hair color of the child are:

S = {R/R, R B, B/R and B/B}

There are four possible outcomes.

Compute the probability that the child will have red hair color as follows:

`P(\text{R})=P(\text{R/R})+P(\text{R/B})+P(\text{B/R})`

`=(1)/(4)+(1)/(4)+(1)/(4)\\\\=(3)/(4)\\\\=0.75`

Thus, the probability that the child will have red hair color is 0.75.

Compute the probability that a child of these parents will have the blond / blond genotype as follows:

`P(\text{B/B})=(1)/(4)=0.25`

Thus, the probability that a child of these parents will have the blond / blond genotype is 0.25.
