Parthenogenesis is a form of asexual reproduction in which an organism develops from an unfertilized egg or ovum. In this process, the egg cells undergo development into a new individual without the need for fertilization by sperm. Parthenogenesis is observed in various species, including certain insects, reptiles, and plants.
There are different types of parthenogenesis, including:
-
Obligate parthenogenesis: Where the species entirely relies on parthenogenesis for reproduction, and males are absent or extremely rare.
-
Facultative parthenogenesis: Where organisms can reproduce both sexually and asexually, depending on environmental conditions.
Parthenogenesis can lead to offspring that are genetically identical to the parent, making it a rapidly efficient reproductive strategy under certain circumstances, especially in environments where mates are scarce.
