Neomyxine biplinicata is an eel-like hagfish. When they sense a threat, they excrete a substance from their pores that turns into a jelly-like fluid when mixed with water.

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?

What type of genetic drift would be simulated if all the beans that were not selected died out?
