Significance of Meiosis:

1. Reproduction and inheritance:

The significance of meiosis for reproduction and inheritance was described…. by German biologist August Weismann, who noted that meiosis was…. transform one diploid cell into four haploid cells if the number of chror…. to be maintained

       2; Essential for sexual reproduction:                                                                                                             

Meiosis is essential for sexual reproduction and therefore …. includes single-celled organisms that reproduce sexually…. archaea or prokaryotes, which reproduce asexually by bi….

      3; Diploid gamete:

Humans, for example, are diploid creatures. The diploid gamete-mother cells undergo meiosis to produce haploid gametes, which are spermatozoa in males and ova in females. These gametes then fertilize, producing a diploid zygote. The zygote undergoes repeated mitosis and develops into a new organism.

      4; Haploid gametes:

Many fungi and many protozoa are haploid. Such organisms produce haploid gametes through mitosis. When two gametes fuse, they form a diploid zygote, which undergoes meiosis immediately, creating four haploid cells. These cells undergo mitosis to create the haploid organismAlternation of generations:

Plan's life cycle shows alternation of generations. The cells of the diploid sporophyte generation undergo meiosis to produce haploid spores, which grow into haploid gametophyte generations. The haploid gametophyte generation produces haploid gametes through mitosis. The gametes combine to produce the diploid zygote. The zygote undergoes repeated mitosis to become the diploid sporophyte.

      5; Genetic Variation:

Because the chromosomes of each parent undergo genetic recombination during meiosis, each gamete, and thus each zygote, will have a unique genetic makeup. In other words, meiosis and sexual reproduction produce genetic variation. Thus, meiosis allows a species to bring variations to handle the changes in the environment.
