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.
卓越的空间能力可能作为一种X连锁隐性性状遗传。由于X连锁隐性性状的性别比例取决于隐性等位基因的基因频率，爱斯基摩人空间能力不存在性别差异可能反映出该隐性等位基因在爱斯基摩人群体中的频率异常高。
