White-throated Sparrows demonstrate that traits we usually associate with sex can be influenced by genes that are not on sex chromosomes

White-throated Sparrows help us see past the sex binary by forcing us to acknowledge sources of variability other than sex, which is, in reality, only a small contributor to variability for many species. Diversity and plasticity of phenotypic expression is the norm, particularly for traits that correlate with sex. Sex-related traits are simply not hardwired.
