Why is genetic essentialism flawed as an explanation for athletic performance?

• A. Genetic variation is largely within racial groups.
• B. Race determines genetic makeup and performance differences are mostly genetic.
• C. Genetics alone determine performance; environment has little effect.
• D. Genetic variation is largely within racial groups; performance is shaped by training, nutrition, access, and environment.

Answer: (D)

Genetic essentialism is flawed because race is not a precise predictor of the genetic makeup that shapes athletic ability, and because performance results from a mix of biology and environment. In reality, most genetic variation lies within racial groups, not between them, so belonging to a particular race does not determine the specific genes relevant to traits like endurance, strength, or recovery. At the same time, athletic performance is strongly influenced by non-genetic factors: training quality and volume, nutrition, rest, injury history, access to coaching and facilities, socioeconomic context, and opportunities to compete. These environmental and social factors interact with biology in complex ways, sometimes enhancing or tempering genetic potential. This combination—genetic variation distributed within races plus the decisive impact of environment and training—explains why relying on race as a stand-in for genetics and performance is not a valid explanation.
