Evolutionary genetics and ecology of sperm-dependent parthenogenesis

open access: yes, 1998
Sperm-dependent (or pseudogamous) forms of parthenogenetic reproduction occur in a wide variety of animals. Inheritance is typically clonal and matroclinous (of female descent), but sperm are needed to initiate normal development.

Genetic homogeneity between two populations of the parthenogenetic lizard Aspidoscelis cozumela Homogeneidad genética entre dos poblaciones de la lagartija partenogenética Aspidoscelis cozumela

open access: yesRevista Mexicana de Biodiversidad, 2008
We used skin-grafting to assess the genetic variability between 2 populations of the parthenogenetic lizard Aspidoscelis cozumela. We transplanted 238 skin fragments among individuals of 2 coastal populations at Cozumel Island.

Contagious parthenogenesis, automixis, and a sex determination meltdown

open access: yes, 2010
Because of the twofold cost of sex, genes conferring asexual reproduction are expected to spread rapidly in sexual populations. However, in reality this simple prediction is often confounded by several complications observed in natural systems. Motivated

Aspectos éticos en el empleo de las células madre Ethical aspects in the use of stem cells

open access: yesRevista Cubana de Hematología, Inmunología y Hemoterapia, 2007
En los animales superiores, las células madre pueden ser embrionarias y somáticas o adultas, según su estado evolutivo. En la actualidad se mantiene una extraordinaria polémica sobre qué células madre utilizar: las embrionarias o las adultas, debate en ...

Cyclical Parthenogenesis in Crustaceans

open access: yes, 2018
Apomixis is the replacement of sexual reproduction with asexual reproduction in plants. Some scientists hypothesize that apomixis is caused by genetics that evolved after sexual reproduction and apomixis mutated from sexual reproduction.
