Describe the biological significance of meiosis.

In animals and humans, meiosis leads to the formation of haploid germ cells – gametes. During the subsequent process of fertilization (gamete fusion), the new generation organism receives a diploid set of chromosomes, which means that it preserves the karyotype inherent in this type of organism. Therefore, meiosis prevents the increase in the number of chromosomes during sexual reproduction. Meiosis also provides combinational variability – the emergence of new combinations of hereditary inclinations with further fertilization.
