Abstract. Sexual dimorphism refers to differences in size and shape between females and males of the same species. The term sexual dimorphism is usually used only for the secondary sexual characteristics, which are unrelated to reproduction. Some examples of sexual dimorphism include differences in stature, weight, morphology of the face, cognitive

Although sexual size dimorphism has a clear evolutionary basis and is caused by genetic and hormonal factors, socio-cultural factors such as gender role in society and gender typical workload influence the degree of sexual size dimorphism too.

While some sexually dimorphic facial traits are mediated by prenatal exposure to sex hormones 7, dimorphism reaches full The term dimorphism denotes a trait that occurs in two distinct forms or morphs within a given species and traits that differ consistently between males and females are sexual dimorphisms. Sexually dimorphic traits may differ so radically between sexes that they can be reliably used to differentiate males from females. Sexual dimorphism, the differences in appearance between males and females of the same species, such as in colour, shape, size, and structure, that are caused by the inheritance of one or the other sexual pattern in the genetic material.
