Is mitosis or meiosis significant process

Question

For biological diversity, is mitosis or meiosis the more significant process?

Answer 1

Meiosis is the cell division procedure which permits the formation of gametes to sexual reproduction, with aleatory separation of each and every chromosome of the individual homologous pairs. Such gametes can fecundate gametes from other individuals promoting grouping of homologous chromosomes from different individuals. In that way the chromosomal recombination given by meiosis and sexual reproduction forms individuals with dissimilar genetic patrimony from their fathers and therefore promotes biological diversity.

Certain fungi species and plants, for illustration, present sporic meiosis, that is, a structure where half of the chromosomes of the species is produced from meiosis. This structure, by mitosis, builds gametes. Even in this situation diversity comes from meiosis.

Meiosis then is the cell division procedure that in conjunction with genetic mutations is accountable for the biological diversity.

Even in species containing zygotic meiosis the aleatory separation of homologous chromosomes in meiosis makes biological diversity.
