During the fоrmаtiоn оf gаmetes, speciаlized germs cells first divide mitotically and then they undergo meiosis. The following graph is representing DNA content of male testicular cell during sperm formation. In the graph, DNA replication is represented by which numbered part(s) of the cycle?[DNArep] In the graph, G1 is represented by which part(s) of the cycle?[G1phase] Based on the graph, how much DNA is present in a resulting human sperm? [DNAmass] In the graph, at which of the numbered regions would you expect to find cells at metaphase of meiosis I? [Met]
