What does the Teacher's Pet Video: Mitosis and Meiosis give as the main reason for the production of haploid cells during meiosis? a. because the two haploid cells will fuse together to make a new genetically different diploid cell that will form the offspring
b. because both the parents and offspring's diploid cells will then be genetically identical to one
c. because the egg and the sperm will then be able to each form a new diploid offspring through the process of meiosis
D. because the sperm brings all of the father's genes to the egg allowing for the baby to have a different number of chromosomes

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?
