Claim: Studies show the average genetic composition of Mexicans is approximately 50 to 62% Indigenous American, 32 to 45% European, and 4 to 6% African, though these proportions vary across the country.
Verdict: Correct (95% confidence)
Explanation: According to a study published on PMC by Moreno-Estrada et al. (2014), the genetic composition of Mexicans includes approximately 50 to 62% Indigenous American ancestry, 32 to 45% European ancestry, and 4 to 6% African ancestry. This is supported by a Stanford University study (2014) that highlights the vast genetic diversity in Mexico, confirming these proportions. Additionally, a Nature article by Martínez-Cortés et al. (2012) provides similar findings, indicating a predominance of European an...
