- A) Hoe many cells are produced by the end of meiosis II? B) Are the cells produced at the end of meiosis II haploid or diploid? C) Are the chromosomes of the four final meiotic products replicated or nonreplicated?arrow_forwardIf meiosis produce haploid cells, how is the diploid numberrestored for those organisms that spend most of their life cycle in the diploid state? a. DNA replication b. reverse transcription c. synapsis d. fertilizationarrow_forwardGive explanation X and Y chromosomes are not homologs, but in meiosis they do pair and segregate in XY organisms to create 50% haploid gametes with an X chromosome and 50% haploid gametes with a Y chromosome. How is pairing achieved? a. Since all other homologous chromosomes pair, the remaining two chromosomes pair by default. b Pairing proteins are capable of binding to different genes on the X and Y chromosomes, which allows them to pair. c. None of the statements is correct. d. They don't actually pair. Random segregation generally ensures the X and Y chromosomes separate. e.Pseudoautosomal regions that are homologous exist at the tips of both the X and Y chromosomes, and they allow pairing.arrow_forward
