Answer :
Final answer:
Race is a social construct based on physical traits, while ethnicity encompasses shared cultural practices. Genetic markers for skin color are controlled by only a few genes, leading to variations within and not necessarily between racial groups.
Explanation:
Race is a term often associated with physical traits like skin color and hair type. However, physical anthropologists have shown that there are no specific genetic traits exclusive to racial groups. Characteristics such as skin color are dictated by only a handful of genes and do not consistently align with convenient racial classifications.
While ethnicity involves shared cultural practices and social traits, race emphasizes physical characteristics. The concept of race is more of a social construct rather than a valid biological category, with more physical variations seen within races than between races.
It's essential to understand that distinctions based on race are often superficial and do not accurately reflect the vast genetic diversity present within the human population.
