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.
The importance of meiosis in producing haploid gametes is that during the process of separating homologous pairs crossing-over occurs. That is, the alleles are 'shuffled'. Each gamete is genetically unique and therefore variation within a species is promoted.
