  • Parthenogenesis | Definition, Types, Facts | Britannica
    parthenogenesis, a reproductive strategy that involves development of a female (rarely a male) gamete (sex cell) without fertilization It occurs commonly among lower plants and invertebrate animals (particularly rotifers, aphids, ants, wasps, and bees) and rarely among higher vertebrates
  • 10 Animals That Exhibit Parthenogenesis - WorldAtlas

  • Parthenogenesis Definition and Examples - Biology Online
    Parthenogenesis is a method of self-reproduction in which the egg cells develop into offspring in the absence of a mate Thus, parthenogenetic animals and plants may still reproduce their own kind without the need to exert time and effort in looking for a suitable mate
  • Explainer: What Is Parthenogenesis And Can It Help Protect Endangered . . .
