Definition of parthenogenesis
a form of asexual reproduction where growth and development of embryos occur without fertilization
Examples of parthenogenesis in the following topics:
- Animals may reproduce asexually through fission, budding, fragmentation, or parthenogenesis.
- 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.
- 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.
- 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.
