Phenotypical expression of reduced mobility during limb ontogeny in frogs: the knee-joint case.

abstract：Background:Sex ratio distorting agents (maternally inherited symbionts and meiotically-driving sex chromosomes) are common in insects. When these agents rise to high frequencies they create strong population sex ratio bias and selection then favours mutations that act to restore the rare sex. Despite this strong select...
