Reproductive competition and sexual selection [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2017
This paper traces the development of our understanding of the development of different approaches to estimating the strength of reproductive competition and sexual selection in the two sexes, based on measures of the operational sex ratio, the opportunity for sexual selection and contrasts in selection gradients between the sexes.

An Overview of the Function and Maintenance of Sexual Reproduction in Dikaryotic Fungi

Frontiers in Microbiology, 2018
Sexual reproduction likely evolved as protection from environmental stresses, specifically, to repair DNA damage, often via homologous recombination. In higher eukaryotes, meiosis and the production of gametes with allelic combinations different from ...
