While rаciаl cаtegоries have prоfоund social and cultural realities, scientific evidence states that there is no biological basis for how we classify racial groups. Explain this conclusion by addressing both phenotypic and genotypic variation in humans: Part A: Explain why phenotypic traits associated with race, such as skin color, are impossible to categorize into discrete groups. What is the term for these traits, and why does it matter with regard to their variation? Part B: Describe the global patterns of human genetic diversity. Specifically, how does the amount of genetic variation within a traditionally defined racial group compare to the variation between different groups, and what does this mean for biological classification?
