How does parthenogenesis differ from other types of reproduction?

Parthenogenesis is a unique form of asexual reproduction in which offspring are produced without fertilization by a male gamete. This process can occur in various species, including certain insects, reptiles, and even some plants, allowing for the development of embryos from unfertilized eggs. The key distinction here is that parthenogenesis does not involve the combination of genetic material from two parents, which is characteristic of sexual reproduction.

In contrast to parthenogenesis, sexual reproduction requires the fusion of gametes from two parents, resulting in offspring that are genetically diverse due to the mixing of DNA. This highlights how parthenogenesis is fundamentally different as it leads to offspring that are genetically identical to the mother, barring any mutations.

Furthermore, while some forms of reproduction can occur in plants, parthenogenesis is not limited to them, as it can also be observed in various animal species. Thus, the correct choice emphasizes the defining characteristic of parthenogenesis: the ability to produce viable offspring without the need for fertilization.
