GlossarySexual Dimorphism

differences in appearance between males and females of a species

Sexual dimorphism refers to the differences in appearance between males and females of the same species, beyond the differences in their sexual organs. These differences can include variations in size, color, shape, and the presence of specific physical traits like antlers in male deer or the colorful plumage in male birds. In humans, sexual dimorphism is evident in traits such as body size, muscle mass, and patterns of hair growth.
