What is the significance of meiosis?


Meiosis is the reduction division the reduction in the amount of genetic material.

Significance of meiosis

1. Meiosis maintains the chromosome number from generation to generation. It reduces the chromosome number to half so that the process of fertilisation can restore the original number in the zygote.

2. It has an evolutionary importance as it allows variations to occur. The process of cross-over and the random distribution of homologous chromosomes between daughter cells result in variation in the genetic make-up of the cells. Variations play an important role in evolution.

3. Chromosomal mutations are brought about by the introduction of certain inheritable changes which may be advantageous for an individual.
