Question

Why is meiosis important? Be sure to explain your answer.

Answer 1

Answer:

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

Answer 2

Meiosis is the process in which the parent cell divides twice into four daughter cells containing half the original amount of genetic information, i.e., the daughter cells are haploid. The gametes are produced by meiosis.

Importance of Meiosis

• Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes.
• Meiosis also produces genetic variation by way of the process of recombination.
• It maintains the constant number of chromosomes by halving the same. This is important because the chromosome number doubles after fertilization.
• In this process independent assortment of maternal and paternal chromosomes takes place. Thus the chromosomes and the traits controlled by them are reshuffled.
• The genetic mutation occurs due to irregularities in cell division by meiosis. The mutations that are beneficial are carried on by natural selection.
• Crossing over produces a new combination of traits and variations.
