Good Genes Theory
Whether the mate sampling and choice performed by females in nature influences offspring performance is a controversial issue in theory. A study using pronghorn antelope females engage in an obvious and energetically expensive mate sampling process to identify vigorous males.Female choices converge on a small proportion of males that sire most young. Offspring of attractive males were more likely to survive to weaning .. Furthermore, female choice may be important and unrecognized as a force that can lower population genetic load.
