The mating process is one of the most important mechanisms for maintaining genetic variation in natural populations. The emergence of sexual reproduction turned out to be the most important ...

Conjugation (or mating) of ciliates is a unique phenomenon among living beings. They have sex not for reproduction or pleasure — they seek to increase genetic variation. Scientists from St Petersburg ...

Brian, P. W., Elson, G. W., Hemming, H. G., and Radley, M., J. Sci. Food Agr., 5, 602 (1954).

The relationship between mating reactivity and ability of cells to attach to polystyrene Petri dishes was investigated in six species of the ciliated protozoan Paramecium. Mating reactive-dependent ...

Plant reproduction is highly complex and variable across the kingdom. The emergence of sexual reproduction has contributed to increase plant genetic diversity and enabled the colonisation of new ...

(via Journey to the Microcosmos) How do stentors make more stentors? Does Paramecium reproduce sexually or asexually? Find out on this week's journey as we explore the ways the microcosmos reproduce!

AbstractThe forces driving extra-pair reproduction by socially monogamous females, and the resulting genetic polyandry, remain unclear. A testable prediction of the hypothesis that extra-pair ...

Two novel hypotheses have been proposed that address the 'two-fold cost of sex': one of the biggest enigmas in the evolution of sexual reproduction. Two novel hypotheses have been proposed that ...
