Web1 Jan 2005 · Thermal induction of parthenogenesis (also known as thermal parthenogenesis) in silkworms is an important technique that has been used in artificial … Web1 Oct 2024 · Switching off diapause in the early egg enables subsequent parthenogenetic transgenesis. The induction of ameiotic parthenogenesis into the genetic toolkit of silkworms allows for the generation of a genetically identical population. Since existing parthenogenetic strains are diapausal and current methods of overcoming diapause are …

Web19 Apr 2024 · We conclude that the induction of premeiotic endoreplication in reptiles was independently co-opted at least four times as an essential component of parthenogenetic reproduction and that this mechanism enables the emergence of fertile polyploid lineages within parthenogenetic complexes.

The production of female offspring by parthenogenesis is referred to as thelytoky (e.g., aphids) while the production of males by parthenogenesis is referred to as arrhenotoky (e.g., bees). When unfertilized eggs develop into both males and females, the phenomenon is called deuterotoky. See more Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In See more Parthenogenesis can occur without meiosis through mitotic oogenesis. This is called apomictic parthenogenesis. Mature egg cells are produced by mitotic divisions, and these … See more Gynogenesis A form of asexual reproduction related to parthenogenesis is gynogenesis. Here, offspring are … See more • Dawley, Robert M. & Bogart, James P. (1989). Evolution and Ecology of Unisexual Vertebrates. Albany: New York State Museum. See more Some species reproduce exclusively by parthenogenesis (such as the bdelloid rotifers), while others can switch between sexual reproduction and parthenogenesis. This is called facultative parthenogenesis (other terms are cyclical parthenogenesis, heterogamy or … See more Parthenogenesis is seen to occur naturally in aphids, Daphnia, rotifers, nematodes and some other invertebrates, as well as in many plants. Among vertebrates, strict parthenogenesis is … See more • Androgenesis - a form of quasi-sexual reproduction in which a male is the sole source of the nuclear genetic material in the embryo See more WebIn this study we used parthenogenetic activation (PA) of porcine embryos to test the hypothesis that a low oxygen concentration (5%) could promote porcine embryo development by activating autophagy. Immunofluorescence staining revealed that low oxygen tension activated autophagy and alleviated oxidative stress in porcine PA embryos.
