Parthenogenesis is a form of asexual reproduction in which an offspring develops from an unfertilized egg, leading to the creation of a new individual without the need for fertilization by a male. This process is observed in some plants, invertebrates, and even certain vertebrates like some species of reptiles and amphibians. Parthenogenetic offspring are typically genetically identical to the parent, resulting in a lack of genetic diversity. This reproductive strategy can be advantageous in stable environments where mates are scarce.
