Question

How do meioss bring genetic variation?

Answer 1

Answer:

Genetic variation is increased by meiosis  beacause,During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA.

Explanation:

This produces a unique combination of genes in the resulting zygote.Recombination or crossing over occurs during prophase I. Homologous chromosomes – 1 inherited from each parent – pair along their lengths, gene by gene. Breaks occur along the chromosomes, and they rejoin, trading some of their genes. The chromosomes now have genes in a unique combination.
