WebSignificance of Meiosis. Having genetically different offspring can be advantageous for natural selection. Meiosis has several mechanisms that increase the genetic diversity of gametes produced. Both crossing over and independent assortment (random orientation) result in different combinations of alleles in gametes. WebGametogenesis is the production of gametes from haploid precursor cells. In animals and higher plants, two morphologically distinct types of gametes are produced (male and female) via distinct differentiation programs. Animals produce a tissue that is dedicated to forming gametes, called the germ line. Individual germline cells are called germ ...
