parthenogenesis

Unfertilized egg development

Parthenogenesis is reproduction without fertilization—an egg developing into an offspring without being fertilized by sperm.

It occurs naturally in some insects, reptiles, and plants.

The offspring are typically genetic clones of the mother.

In casual use, any seemingly miraculous or fatherless origin: The project seemed to emerge by parthenogenesis, with no one claiming credit.
