Question

Model: To determine the probability of a trait combination such as black fur and red eyes consider each trait separately. Fill in the Punnett square for each trait. Then determine the probability of black fur and the probability of red eyes. Express each probability as a fraction.

Answer 1

Answer:

3/8

Explanation:

I think I can help with completing the question.

Above each punnet square, the genotypes of the parents were given right? something like this:

Parent 1 fur genotype: Ff                             Parent 1 eye genotype: Ee

Parent 2 fur genotype: Ff                            Parent 2 eye genotype: ee

       F         f                                                              E        e

F     FF       Ff                                                    e     Ee      ee

f      Ff        ff                                                     e     Ee      ee

Probability of black fur if dominant is:               Probability of red eyes:

    3/4                                                                       2/4= 1/2

Probability of a trait combination such as black fur and red eyes is

3/4*1/2 = 3/8.
