| Because hybrid males are almost completely sterile, almost all eggs are unfertilized. |
| 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. |
| 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. |
| During copulation, the female transfers unfertilized eggs to the male's ventral surface, where fertilization takes place. |
| In most ants, females are typically produced by sexual reproduction, while males develop from unfertilized eggs. |
