3.18 Assortative mating. Assortative mating is a nonrandom mating pattern where individuals with simi- lar 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 results.42 Partner (female) Self (male) Blue Brown Green Blue 78 23 13 19 23 12 Brown Green Total 108 11 16 41 9 55 Total 114 54 36 204 (a) What is the probability that a randomly chosen male respondent or his partner has blue eyes? (b) What is the probability that a randomly chosen male respondent with blue eyes has a partner with blue eyes? (c) What is the probability that a randomly chosen male respondent with brown eyes has a partner with blue eyes? What about the probability of a randomly chosen male respondent with green eyes having a partner with blue eyes? (d) Does it appear that the eye colors of male respondents and their partners are independent? Explain your reasoning.
