| In parthenogenesis, an unfertilized egg can start dividing and still produce a normal offspring. |
| Because hybrid males are almost completely sterile, almost all eggs are unfertilized. |
| In most ants, females are typically produced by sexual reproduction, while males develop from unfertilized eggs. |
| Some species consist only of females that produce their daughters from unfertilized eggs, a type of reproduction called parthenogenesis. |
| In these mutants, the meiotic products remain in interphase in unfertilized eggs and undergo inappropriate DNA replication. |
| Next, they took an unfertilized egg from a second sheep and removed its DNA, carefully sucking it out with a thin glass tube called a pipette. |
