parthenogenesis

Examples of parthenogenesis in the following topics:

• Types of Sexual and Asexual Reproduction

  • Animals may reproduce asexually through fission, budding, fragmentation, or parthenogenesis.
  • Parthenogenesis is a form of asexual reproduction where an egg develops into a complete individual without being fertilized.
  • Parthenogenesis occurs in invertebrates such as water fleas, rotifers, aphids, stick insects, some ants, wasps, and bees.
  • Bees use parthenogenesis to produce haploid males (drones) and diploid females (workers).
  • Some vertebrate animals, such as certain reptiles, amphibians, and fish, also reproduce through parthenogenesis.

• Reproductive Cloning

  • Parthenogenesis, or "virgin birth," occurs when an embryo grows and develops without the fertilization of the egg occurring; this is a form of asexual reproduction.
  • An example of parthenogenesis occurs in species in which the female lays an egg.

• Animal Reproduction and Development

  • In contrast, a form of asexual reproduction found in certain insects and vertebrates is called parthenogenesis where unfertilized eggs can develop into new offspring.
  • This type of parthenogenesis in insects is called haplodiploidy and results in male offspring.
