Detailed explanation-1: -Parthenogenesis (Greek: ‘virgin birth’) is a form of reproduction in which an unfertilized egg develops into a new individual. Parthenogenesis occurs naturally in certain plants, arthropods, and insects.

Detailed explanation-2: -Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth, ” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.

Detailed explanation-3: -Parthenogenesis is a form of asexual reproduction by self-impregnation resulting in the production of a zygote from an unfertilized egg. Thus, it is also referred to by many as “virgin birth”. Parthenogenesis takes place in both asexual animals and plants. In animals, the embryo develops from an unfertilized egg.

Detailed explanation-4: -In the thelytoky, the haploid unfertilised egg parthenogenetically develop into females.

Detailed explanation-5: -Parthenogenesis is a unique form of reproduction where embryonic development occurs in unfertilized eggs. Beatty (1967) defined parthenogenesis as ‘the production of an embryo from a female gamete without any genetic contribution from a male gamete and with or without eventual development into an adult’.
