胡须修剪在品系A2 G小鼠中极为常见，发病率随年龄增长而增加。超过75%的包含2-3只小鼠的笼子在小鼠约60日龄时具有1个或多个活性修剪器。当雄性A2 G小鼠与其他品系的小鼠一起饲养时，在A2 G雄性占社会优势的笼中（通过试管试验判断），修剪倾向最多。每个笼子的动物数量似乎不影响这种行为。在雄性老鼠的群体中，通常有一只没有修剪胡须，大概是因为它在社会中占主导地位。然而，对于女性来说，总是有几个活跃的修剪者。有一些证据表明，当雌性怀孕时，它们能够抵制配偶修剪胡须。
Whisker trimming is extremely common in strain A2G mice, with an incidence which progresses with age. Over 75% of cages containing 2-3 mice have 1 or more active trimmers by the time the mice are about 60 days old. When male A2G mice were housed with mice of other strains there was a tendency for trimming to occur most in cages where the A2G male was socially dominant (as judged by a tube test). The number of animals per cage did not seem to influence this behaviour. In groups of male mice there was usually 1 with untrimmed whiskers, presumably because he was socially dominant. However, with females there were always several active trimmers. There was some evidence that when females became pregnant they were able to resist whisker trimming by their mates.
