While the lek paradox describes only those situations where females do not receive direct, resource-based benefits from their mates (Andersson 1994), resolving the lek paradox will have broad implications across mating systems.
WebKnown as the lek paradox, this contradiction has motivated extensive population genetic theory, yet remains unresolved. Recent modeling by Bonduriansky and Day concludes that costly female preference is best maintained when male condition is determined by environmentally induced factors transmitted across single generations. Web5 de abr. de 2001 · A theoretical solution to the lek paradox has been proposed on the basis of two assumptions: that traits are condition-dependent, and that condition shows …
WebOn the resolution of the lek paradox. Directional female mate choice is expected to deplete additive genetic variation in male traits. This should preclude such trait-based … WebThis paper offers a resolution to the lek paradox and rests on only two assumptions; condition dependence of sexually selected traits and high genetic variance in …
Web6 de mar. de 2007 · Of the many potential resolutions to the lek paradox, the ‘genic capture hypothesis’ proposed by Rowe & Houle (1996), has received the most attention in recent years. This idea is based on two criteria: secondary-sexual traits exhibit condition dependence and condition has high additive genetic variance.
