WebThis evolutionary conundrum is known as the lek paradox. Newly proposed resolutions to this paradox aim to unravel mechanisms that contribute to the persistence of genetic variance in traits under directional female mate choice. Original language: English: Pages (from-to) 1-3: Journal: Web1 de mar. de 2016 · Known 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.

Web25 de mar. de 2024 · The genic capture hypothesis, where sexually selected traits capture genetic variation in condition and the condition reflects genome-wide mutation load, stands to explain the presence of abundant genetic variation underlying sexually selected traits. Web1 de jan. de 2024 · However, empirical tests of such hypotheses are rare and future work is required to determine which explanations represent likely resolutions to the lek paradox. Conclusions Leks continue to provide rich systems for the study of male courtship behavior and female selection of good genes in varied taxa. philosophy toiletries

This renders sexually selected traits particularly susceptible to inbreeding depression, due to relatively low ratios of additive genetic variance to dominance variance.
