Selection leads to genetic improvement but also reduces genetic variation in the progeny. When all animals in a population are closely related there is little genetic variation and little scope for further genetic progress. Mate selection procedures are used to help maintain genetic variation, and hence genetic progress, in the future and to avoid the fitness problems related to severe inbreeding.

Correlated evolution of mate signals and mate preference may be constrained if selection pressures acting on mate preference differ from those acting on mate signals. In particular, opposing selection pressures may act on mate preference and signals when traits have sexual as well as nonsexual functions. In the butterfly Colias philodice eriphyle, divergent selection on wing color across an ele...

A computational study is conducted to evaluate the hypothesis that mate selection is the evolutionary origin of communication. A population of neural networks is evolved for two cooperative tasks mate selection and prey capture. Simple codes developed for mate selection serve as an effective stepping stone for prey capture but not vice versa. Mate selection followed by an additional prey captur...

This research set out to find out the mate selection criteria among single female teachers. This qualitative study was carried out via thematic analysis approach. Using purposive sampling method, 15 single female teachers aged 18 to 30 years old were identified in Tehran and fifteen semi-structured interviews were conducted. The interviews were recorded, transcribed and then were analyzed using...
