Allelic frequencies of the MN blood group and environmental data from 30 African population samples were tested with multiple regression to test the hypothesis that MN frequencies vary with climate. Allelic frequencies were related to environmental variation (P < 0.01), and factor analysis of the data generated the hypothesis that the M allele of the MN polymorphism increased in frequency with decreasing environmental temperatures.
