Question

What is the probability that both people in a couple will have green eyes? Assume the couple is randomly chosen.

2.20 Assortative mating. Assortative mating is a nonrandom mating pattern where individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern. Researchers studying this topic collected data on eye colors of 204 Scandinavian men and their female partners. The table below summarizes the 65 results. For simplicity, we only include heterosexual relationships in this exercise. Partner (female) Blue Brown Green Total Blue 78 23 13 114 12 Brown 19 54 Self (male Green 11 16 36 204 Total 108 55 41

Explanation / Answer

total couples where both make and female have green eyes = 16

total couples surveyed = 204

probability that both people in a couple randomly selected will have green eyes =

        couples where both have green eyes / total couples

             = 16 / 204

Hence probability = 0.07843
