Final answer:
Race is socially constructed and not a biological concept. Personal genomic research does not support racial categories.
Step-by-step explanation:
Race is socially constructed and is not a biological concept. While there are genetic markers for physical characteristics, such as skin color and hair texture, only a few of these markers align with the convenient categories we use to categorize race. The concept of race has changed across cultures and eras and has become less connected with ancestral and familial ties, and more concerned with superficial physical characteristics. Additionally, personal genomic research does not support the idea of racial categories, as there is more genetic variation within a racial category than between different racial categories.
