What is the purpose of meiosis? Where does it occur, what is produced, why does it occur or what are the significances and what are the consequences if it does not occur?

Expert Solution

  • Meiosis is a type of cell division in which the daughter cells have half the number of chromosomes as compared to that of parent cells.
  • It takes place in germ cells , and four haploid gametes are produced. It also takes place in plants (spores).
  • It is important because to maintain a diploid set of chromosomes in sexual reproduction, fertilisation of a diploid male gamete with diploid female gamete would result into a tetraploid zygote, which won't survive. However, due to meiosis , haploid gametes are produced which produce a diploid zygote upon fertilisation.
  • Also, meiosis leads to genetic recombination and introduces variations in the population.
  • Without meiosis, sexual reproduction won't be possible and there would be lesser genetic diversity overall.

Meiosis (what cells are produced by this process?): • Location of meiosis (where are gametes (eggs and sperm) produced?) • How many cells are produced from meiosis? Are they haploid or diploid? Are they genetically unique or clones of the parent cell? • Know that crossing over between chromosomes and independent assortment of chromosomes are the source of genetically unique gametes and offspring.
