In animals, parthenogenesis means the development of an embryo from an unfertilized egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg.

Understanding the Context

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. Parthenogenesis, which derives from Greek and translates to “virgin birth”, is a type of asexual reproduction in which the offspring of some species develops from the egg or female gamete without first being fertilised by the male gamete. Parthenogenesis is a reproductive process in which a female can produce an embryo without prior fertilization of an egg with sperm.

Key Insights

Some of the parthenogenesis examples include invertebrates such as ants, wasps, aphids, bees, etc. Parthenogenesis in plants is less common than in animals. Parthenogenesis is a natural form of asexual reproduction where an embryo develops from an unfertilized egg. The term originates from Greek, combining “parthenos” (virgin) and “genesis” (creation). Parthenogenesis is a type of asexual reproduction at which the female gamete develops into the offspring without being fertilized by a male gamete.

Final Thoughts

Parthenogenesis represents a distinctive form of asexual reproduction wherein embryos originate from unfertilized eggs. Once considered merely a biological anomaly, it has now been documented across a wide range of taxa, including invertebrates, vertebrates, and plants. The meaning of PARTHENOGENESIS is reproduction by development of an unfertilized usually female gamete that occurs especially among lower plants and invertebrate animals.
