Research has shown that a person's height is about 81 percent heritable, whereas his or her body mass index (BMI) is about 59 percent heritable. Which of the following is the most accurate interpretation of these findings? a. The variability we see in a population's height is more influenced by genetic factors than the variability we see in the population's weight. b. Environmental factors
account for only 19 percent of a person's height and 41 percent of a person's BMI. c. We cannot make any conclusions about genetic contributions to either height or weight. d. Knowing the relative genetic contributions to traits such as height or weight does not allow us to compare these two unrelated characteristics of people.

female? (a) You have many, many opportunities to have children over your lifetime. (b) It is more likely that you will choose a man who will not have a sexual affair with another woman.
