On the resolution of the lek paradox
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. 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.
