Web6 de mar. de 2007 · explored the lek paradox and several have proposed promising resolutions (table 1). 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. WebAnother potential resolution to the lek paradox is Rowe and Houle's theory that sexually selected traits depend on physical condition, which might in turn, summarize many genetic loci. [52]
WebThe antagonistic pleiotropy hypothesis was first proposed by George C. Williams in 1957 as an evolutionary explanation for senescence. Pleiotropy is the phenomenon where one gene controls for more than one phenotypic trait in an organism. A gene is considered to possess antagonistic pleiotropy if it controls more than one trait, where at least one of … Web22 de abr. de 1995 · The higher genetic variability of sexual traits is contrary to the expectations of the lek paradox.
