Aspecies is a group of organisms capable of mating and producing offspring, and speciation is the process of forming a new species. one way a new species may form is by geographic isolation. this occurs when members of a population are physically separated, for example, by a river, or a desert. after the separation the two populations, responding to different conditions, will adapt differently, and so their evolutionary paths will a) converge. b) dissect. c) diverge. d) reverse.

Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?
