Sperm quality of spontaneously occurring gynogenetic males in the yellowtail tetra Astyanax altiparanae
(2021-01-01)
Gynogenesis is a chromosomal manipulation technique where an offspring is generated exclusively from maternal inheritance. In the yellowtail tetra (Astyanax altiparanae) almost all gynogenetic fish were females, suggesting ...

Dynamic sequence evolution of a sex-Associated b chromosome in lake Malawi cichlid fish
(2017-01-01)
B chromosomes are extra chromosomes found in many species of plants, animals, and fungi. B chromosomes often manipulate common cellular processes to increase their frequency, sometimes to the detriment of organismal fitness. ...
The first case of induced gynogenesis in Neotropical fishes using the yellowtail tetra (Astyanax altiparanae) as a model organism
(Elsevier B.V., 2020-01-01)
Gynogenesis is a chromosome manipulation technique applicable on the production of all-female populations, generation of inbred or clonal lines and identification of genetic sex determination mechanisms in fish. Therefore, ...
B Chromosomes in Psalidodon scabripinnis (Characiformes, Characidae) Species Complex
(Mdpi, 2022-09-01)
Simple Summary For more than a century, B chromosomes have been investigated in several eukaryotic species. These supernumerary genomic elements behave as parasites or provide fitness benefits to the hosts. They are mostly ...
