A Genetic Explanation for No Sex Difference in Spatial Ability among Eskimos

Superior spatial ability may be inherited as an X-linked recessive trait. Since the sex ratio for an X-linked recessive trait depends on the gene frequency of the recessive allele, the absence of a sex difference in Eskimo spatial ability may reflect an unusually high frequency of the recessive alle...

Description
Summary:Superior spatial ability may be inherited as an X-linked recessive trait. Since the sex ratio for an X-linked recessive trait depends on the gene frequency of the recessive allele, the absence of a sex difference in Eskimo spatial ability may reflect an unusually high frequency of the recessive allele in the Eskimo population.
