Summary: parthenogenesis in Brief
Parthenogenesis [pahr-thuh-noh-jen-uh-sis] is a type of asexual reproduction where an unfertilized egg develops into a new individual. It is common in insects and some other arthropods, but rare in vertebrates. The term encompasses obligate and facultative parthenogenesis, and artificial parthenogenesis. Parthenogenesis has important implications for genetics and evolutionary biology.
