Detailed Solution

The key features of meiosis are as follows: l Meiosis involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication. l Meiosis I is initiated after the parental chromosomes have replicated to produce identical sister chromatids at the S phase. l Meiosis involves pairing of homologous chromosomes and recombination between non-sister chromatids of homologous chromosomes. l Four haploid cells are formed at the end of meiosis II
