Which of the following is the best description of sexual selection? a. Sexual selection is the differential reproductive success due to variation in acquiring immunity from mates. b. Sexual selection is the differential reproductive success due to variation in survival from social selection. c. Sexual selection is the differential reproductive success due to variation in acquiring mates or mating success. d.

Normally, male red ducks only try to mate with females of their own species. A researcher swapped eggs between the nests of red ducks and blue ducks (a different species) and found that if male red ducks were raised by female blue ducks, later in life they only tried to mate with female red ducks. Which of the following inferences is supported by these results? Group of answer choices The mate preference of male red ducks is environmental. The mate preference of male red ducks is genetic. The mate preference of male red ducks is innate. The mate preference of male red ducks is learned.
What does positive assortive mating mean? a. Individuals that are different for a certain trait are more likely to mate b. Individuals that are alike for a certain trait are less likely to mate c.

Which is an example of disruptive selection? Group of answer choices Drug resistance increases with each generation; the resistant bacteria survive, and the nonresistant bacteria get killed off. Swiss starlings usually lay four or five eggs, thereby increasing their chances of more offspring. Over time, Equus developed strength, intelligence, speed and durable grinding teeth. Panay island snails mainly have two different phenotypes, black and white shells.
