The significance of meiosis :-. 1. It maintains the same chromosome n umber in the sexually reproducing organisms. From a diploid cell, haploid gametes are produced which in turn fuse to form a diploid cell. 2. It restricts the multiplication of chromosome number and maintains the stability of the species. 3. Maternal and paternal genes get exchanged during crossing over.
Introduction. Meiosis, the form of cell division unique to egg and sperm production, sets the stage for sex determination by creating sperm that carry either an X or a Y sex chromosome.his means that when the chromosomes of egg and sperm cells combine at fertilization, the embryo regains the normal diploid number. Meiosis mixes up the parental genes in two ways. First, the members of each chromosome pair come together and swap segments in a process known as crossing over, or recombination.
