The variability is in the sex chromosomes.

Evolution; international journal of organic evolution - 1 Dec 2013

Reinhold Klaus, Engqvist Leif

Abstract excerpt

Sex differences in the mean trait expression are well documented, not only for traits that are directly associated with reproduction. Less is known about how the variability of traits differs between males and females. In species with sex chromosomes and dosage compensation, the heterogametic sex is expected to show larger trait variability ("sex-chromosome hypothesis"), yet this central prediction, based on...
