Explain the function of meiosis.?

Answer 1

Meiosis facilitates stable sexual reproduction. Without the halving of ploidy, or chromosome count, fertilization would result in zygotes that have twice the number of chromosomes than the zygotes from the previous generation. Successive generations would have an exponential increase in chromosome count, resulting in an unwieldy genome that would cripple the reproductive fitness of the species. Polyploidy, the state of having three or more sets of chromosomes, also results in developmental abnormalities or lethality.

Most importantly, however, meiosis produces genetic variety in gametes that propagate to offspring. Recombination and independent assortment allow for a greater diversity of genotypes in the population. As a system of creating diversity, meiosis allows a species to maintain stability under environmental changes.

Answer 2

Meiosis produces sex cells (sperm or eggs). Unlike mitosis, the daughter cells are not identical which is what creates genetic diversity.

Answer 3

It plays a part in growth,cell replacement and repair,and in sexual reprodction
