Quick Summary

Diploid parthenogenesis is a form of reproduction where a female gamete develops into a new individual without fertilization, resulting in diploid offspring. This means the offspring have a full set of chromosomes, identical to the parent. This process can occur through automixis, where a haploid cell duplicates its chromosomes or combines with another haploid cell, or apomixis, where diploid egg cells are produced through mitosis, creating genetic clones of the parent. Diploid parthenogenesis is observed in various species, including insects like aphids, rotifers, and some flowering plants. It is considered an incomplete form of sexual reproduction because it originates from gametes.12

Parthenogenesis
…from a male gamete (diploid parthenogenesis). Even if males were present, sperm could not fertilize the eggs because the latter are already diploid. Under conditions of environmental stress such as seasonal changes, some females form eggs that undergo reductional division, resulting in eggs with the haploid number of chromosomes;…
