Let me share with you a difference between sexual reproduction and parasexuality.

AspectSexual ReproductionParasexuality
Present inAll EukaryotesMostly observed in fungi e.g. Candida albicans
Formation of gametesFormation of specialized reproductive cells (gametes) with half the normal chromosome numberNo formation of gametes; genetic material is exchanged between cells without the formation of specialized structures
Fusion of GametesFusion of gametes (syngamy) to restore the full chromosome numberExchange of genetic material is achieved through cell-cell fusion or hyphal fusion
VariationResults in significant genetic variation and introduces new combinations of genesResults in genetic recombination but without the same level of variation as sexual reproduction
Formation of sporesMay involve the formation of specialized structures (spores) for dispersalDoes not necessarily involve the formation of spores
Role in evolutionContributes to the long-term evolution of populations by creating diverse genotypesFacilitates genetic adaptation and survival without the need for the generation of sexual structures or gametes
