Meiosis is the process by which cells are produced from a cell that was originally diploid. True or false?.

Respuesta :

True; meiosis is the process by which cells are produced from a cell that was originally diploid.

What is meiosis?

  • The production of offspring by sexual reproduction includes the fusion of two gametes, each with a complete haploid set of chromosomes. Gametes are formed from specialised diploid cells.
  • This specialised kind of cell division that reduces the chromosome number by half results in the production of haploid daughter cells. This kind of division is called meiosis.
  • Meiosis ensures the production of haploid phase in the life cycle of sexually reproducing organisms whereas fertilisation restores the diploid phase.
  • Meiosis occurs during gametogenesis in plants and animals. 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 them.
  • Four haploid cells are formed at the end of meiosis II.
