Question

What causes the differences in physical characteristics like hair color among people?

Answer 1

Answer:

Hey Buddy here's ur answer

It is because the dominant traits of the parent.

Explanation:

In genetics, the physical characteristics are referred as phenotype. Each character such as hair color in offspring is determined by a pair of genes. One gene is inherited from father and other gene is inherited from mother. The phenotype is determined by the dominant gene. The recessive gene of a pair does not show its effect in heterozygous condition. Therefore, the offspring inherits a dominant gene and a recessive gene then the dominant gene will show the character. This is called Mendel’s law of dominance.

Answer 2

It has to do with pheomelanin and eumelanin

Explanation:

According to explorebiotech.com, "low concentrations of the eumelanin pigment will yield blonde hair, while high concentrations result in darker brown hair. People with natural red hair have much higher pheomelanin levels in their hair than people with more common hair colors like brown, blonde, and black."
