Sexual selection for males with beneficial mutations
Sexual selection is the process by which traits providing a mating advantage are favoured. Theoretical treatments of the evolution of sex by sexual selection propose that it operates by reducing the load of deleterious mutations.

Postcopulatory sexual selection [PDF]
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to generate a startling diversity of morphological, behavioural and physiological adaptations.

The impact of COVID-19 on sexual health: a preliminary framework based on a qualitative study with clinical sexologists [PDF]
Introduction: In recent months, some attempts were made to understand the impact of COVID-19 on sexual health. Despite recent research that suggests COVID-19 and lockdown measures may eventually impact sexual response and sexually related behaviors, we ...

Intralocus sexual conflict diminishes the benefits of sexual selection. [PDF]
Evolution based on the benefits of acquiring "good genes" in sexual selection is only plausible with the reliable transmission of genetic quality from one generation to the next.

Sexual Selection and Sexual Dimorphism in Mottled Sculpins [PDF]
There are two aspects to sexual selection (Darwin, 1871). Intra-sexual selection focuses on the consequences of competition between members of one sex (usually males) for access to the other sex; whereas epigamic selection or female choice focuses on the consequences of mate preferences of one sex (usually females) with regard to the other sex ...
