Diplontic selection may occur when diploid (or lower ploidy) cells (having less DNA) can replicate and divide faster than neighboring higher ploidy cells (Dermen, 1953; Klekowski, 2003) . To return to a haploid stage, meiosis must occur (see Cell division). It has a Haplodiplontic life cycle. The Haplo-Diplontic life cycle is observed in 8 following plants. Other definition of diplontic is of or relating to an animal or plant that has the diploid number of chromosomes in its somatic cells. The main plant body is thallus, which is diploid. In the whole cycle, zygotes are the only diploid cell; mitosis occurs only in the haploid phase. In the life cycle diagram, the zygote is alone on the diploid portion. Harrison, D. and M. Slee.

CAS Haploid is the quality of a cell or organism having a single set of chromosomes. Heteromorphic alternation of generation occurs in organisms in which the haploid gametophyte phase and diploid sporophyte phase are different in form. In plants like Polysiphonia the haploid plant (gametophyte) produces diploid zygote after gametic fusion. 1) Gametes undergo meiosis and diploid sporophyte is the dominant and independent phase. This produces tetrasporangia where meiosis takes place and produces haploid tatraspores. The first is a dominant, concurrent sporophyte phase and the second is a brief gameto-phyte phase; both phases are multicellular so somatic growth follows meiosis and somatic growth follows the union of gametes or syngamy.
