From: Prevalence of sexual dimorphism in mammalian phenotypic traits

The role of sex in explaining variation in phenotypes of wildtype mice as assessed using data from the IMPC. (a,b) The proportion of experiments where sex had a significant role in wildtype phenotype. (a) Categorical data sets (n=545). (b) Continuous data sets (n=903). (c,d) The distribution of classifications when analysed by institute (c: categorical data sets, d: continuous data sets).
