Racial Classification

Racial criteria, racial traits in relation to heredity and environment; biological basis of racial classification, racial differentiation and race crossing in man.

1.differences due to accident.(diseases)

2.differences due to adaptive response during the lifetime of the individual(climatic)

3.differences due to cultural influences(natural selection).
