Genetic Significance of Meiosis
The meiosis has following genetic significances:
The basic cytogenetical significance of meiosis is the formation of four monoploid (haploid) nuclei from a single diploid one, in two successive divisions, thus balancing of chromosome number that results from syngamy (fertilization).
The crossing over which occurs in its prophase I, provides new combinations of genetical substance and hence new combinations of characters in offsprings.
The two members of a homologous pair of chromosomes pass on two different daughter cells.
