Question

How can hair be used as a trait to differentiate between people ​

Answer 1

Answer:

Many genetic variations are responsible for different hair traits among people of different regions and ethnic groups.

Explanation:

Gene mutations play an important role in hair color, texture, thickness, and stability. For instance, normal variation (polymorphism) is two genes FGFR2 and EDAR cause a difference in the hair thickness of Asian people.

These are the additional genes that are associated with hair traits of different populations.

Answer 2

Answer:

Genetic factors appear to play a major role in determining hair texture—straight, wavy, or curly—and the thickness of individual strands of hair. Studies suggest that different genes influence hair texture and thickness in people of different ethnic backgrounds.
