Abstract The coexistence of different mating strategies, whereby a species can reproduce both by selfing and outcrossing, is an evolutionary enigma. Theory predicts two predominant stable mating states: outcrossing with strong inbreeding depression o

Trioecy, a mating system in which males, females and hermaphrodites co-exist, is a useful system to investigate the origin and maintenance of alternative mating strategies. In the trioecious nematode Auanema rhodensis, males have one X chromosome (XO

The X chromosome is a potential polarising signal for asymmetric cell divisions in meiotic cells of a nematode

Autor: Talal Alyazeedi, Emily Xu, Jasmin Kaur, Diane Shakes, Andre Pires-daSilva

The unequal partition of molecules and organelles during cell division results in daughter cells with different fates. Asymmetric cell divisions have been best characterised in systems in which extrinsic signals polarise the mother cell during cell d
