Sex-ratio meiotic drive occurs when males produce a predominance of X-chromosome bearing sperm and an inordinate number of daughters. A driving X causes highly female-biased sex ratios and the risk of extinction. Polyandry can rescue a population from extinction.
当雄性产生大量携带 X 染色体的精子和过多的雌性后代时，就会出现性比减数驱动。一个驱动 X 会导致高度雌性偏斜的性别比和灭绝的风险。多配偶制可以拯救一个面临灭绝的种群。
