How many cycles of nuclear and cell division occur during meiosis?

Step-by-step solution

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