In broad terms, the heritability of a trait measures the extent to which differences among members of a population can be explained by differences in their genetics.
广义上讲，性状遗传性衡量的是群体成员间的差异在多大程度上可以用基因差异解释。

Nonetheless, new research on cod genetics suggests that fishing is changing the population in ways that could lead to a partial collapse.
然而最近对于鳕鱼遗传学的研究表明，过度捕捞正在改变鳕鱼的种群，甚至有可能使部分种群消失。
