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 … 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.
