![]() The zebra shark ( Stegostoma fasciatum) can alternate between sexual and asexual reproduction by parthenogenesis. Parthenogenesis has been observed in some types of sharks, such as the blacktip shark, the bonnethead shark, and the zebra shark. Parthenogenesis may occur in some vertebrate animals as well, such as amphibians, some fish, reptiles, and in few bird species. Parthenogenesis occurs in many types of invertebrates including scorpions, nematodes, mites, water fleas, wasps, some bees, and other insects. In plants, it is a part of the process, apomixis. In animals, the embryo develops from an unfertilized egg. Thus, it is also referred to by many as “virgin birth”. Parthenogenesis takes place in both asexual animals and plants. What is parthenogenesis? Is parthenogenesis an asexual reproduction? Parthenogenesis is a form of asexual reproduction by self-impregnation resulting in the production of a zygote from an unfertilized egg. Join us and participate in our Forum: Asexual and sexual reproduction differences This is seen in organisms that reproduce solely by asexual means. Instead, they give their full genome to the offspring by a method similar to mitosis. ![]() In contrast, organisms that reproduce asexually may not divide by meiosis to form gametes. Sexual reproduction is the most common method of reproduction in multicellular eukaryotes, such as plants, fungi, and mammals. For example, animals sexually reproduce via a haploid egg cell (also called an ovum) and a haploid sperm cell to produce a diploid zygote. In biology, sexual reproduction is defined as a mode of reproduction wherein a gamete containing only one set of chromosomes ( haploid) combines with the other gamete to form a diploid offspring. There are two types of reproduction: sexual and asexual reproduction. The process is referred to as reproduction, which is one of the features of a living thing. To reproduce, by definition, means to produce new offspring. Disadvantages of Parthenogenesis as a Form of Reproduction. ![]() ![]() Benefits of Parthenogenesis as a Form of Reproduction. ![]()
