what is the significance of meiosis
Answers
Explanation:
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.
Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction.
It activates the genetic information for the development of sex cells and deactivates the sporophytic information.
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.
