Table 2. Effect of covariates on mean MtHz.
The pc values are from principal components analysis. Autosomal variance refers to the variability from homozygosity at autosomal positions. Haplogroup values are compared to haplogroup H (n = 72,363). The number of individuals with each haplogroup is noted.
