Mention the key features of meiosis.

Explanation

Key features of Meiosis :
`1)` Meiosis is involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication.
`2)` Meiosis I is initiated after the parental chromosomes have replicated to produce indentical sister chromatids at the S-phase.
`3)` Meiosis involves pairing of homologus chromosomes and recombination between them.
`4)` Four heploid cells are formed at the end of Meiosis - II.
