| We also isolated several mutants that produce unfertilized eggs or show an early arrest in embryonic development. |
| In parthenogenesis, an unfertilized egg can start dividing and still produce a normal offspring. |
| This process is known as parthenogenesis, where unfertilized eggs develop into embryos without sperm. |
| Some species consist only of females that produce their daughters from unfertilized eggs, a type of reproduction called parthenogenesis. |
| In most ants, females are typically produced by sexual reproduction, while males develop from unfertilized eggs. |
| Because hybrid males are almost completely sterile, almost all eggs are unfertilized. |
