Single Choice

Which of the following is not a feature of meiosis?

AMeiosis involves two sequential cycles of nuclear and cell division, meiosis I and meiosis II but only a single cycle of DNA replication.
BMeiosis I is initiated after the parental chromosomes have replicated to produce identical sister chromatids at the S - phase.
CMeiosis involves pairing of non-homologous chromosomes and recombination between them.
Correct Answer
DFour haploid cells are formed at the end of meiosis II.

Solution

Meiosis, as we know, is called as Reductional division where the number of chromosomes is reduced to half from parent to daughter cell. It involves two cycles - Meiosis I and Meiosis II where nuclear and cell division takes place but DNA replication takes place once only. While meiosis I take place after the cell has completed the replication of DNA of parent material and thus identical sister chromatids is formed. While since it is a reductional division so we know four daughter cells are formed having half the number of chromosomes as of parent cell. Moreover, Meiosis never involves the pairing of non-homologous chromosomes and no recombination occurs between them.
So, the Incorrect statement with respect to meiosis is 'Meiosis involves the pairing of non-homologous chromosomes and recombination between them.'.
