Question

It has been suggested that genetic correlation between the expressions of a trait in the two sexes is responsible for some apparently non-adaptive traits, such as nipples in men and the muted presence in many female birds of the bright colors used by males in their displays. Suggest ways of testing this hypothesis. What other traits might have evolved because they are genetically correlated with adaptive traits, rather than being adaptive themselves?

Answer 1

- Sexual dimorphism alludes to contrasts fit as a fiddle among females and guys of similar species. The term sexual dimorphism is normally utilized distinctly for the auxiliary sexual qualities, which are random to generation. A few instances of sexual dimorphism remember contrasts for height, weight, morphology of the face, subjective turn of events, mortality, and sickness commonness. In spite of the fact that people display low degrees of sexual dimorphism contrasted with different creatures, contrasts among females and guys are various. Developmental, explicitly dimorphic characteristics create through the procedure of sexual choice. Besides, mating framework, body size, sex jobs, and nature of condition additionally assume a significant job in deciding the degrees of sexual dimorphism. Sexual dimorphism has a significant spot in natural humanities. In bioarchaeology and measurable human studies, morphological and metric attributes are utilized to gauge sex of the skeletal remains, while in investigations of human development the degree of sexual dimorphism is utilized to reproduce social conduct.

- it's not the adaptive trait it's a genetic trait

adaptive trait are those which organism adapt in there lifetime
