人类群体之间的遗传差异通常是Y染色体大于mtDNA（1-3）。一个可能的解释是，由于普遍存在的父系居住现象，即妇女在结婚后搬到其配偶的住所，女性的移徙率高于男性。为了验证这一假设，我们比较了三个matrilocal（其中该名男子结婚后搬到他的配偶的住所）和三个patrilocal组之间的北方泰国的山地部落的线粒体DNA和Y染色体变异。这些群体的遗传多样性与居住模式表现出惊人的相关性，支持了性别特异性迁移在影响人类遗传变异方面的作用。
Genetic differences among human populations are usually larger for the Y chromosome than for mtDNA(1-3). one possible explanation is the higher rate of female versus male migration due to the widespread phenomenon of patrilocality, in which the woman moves to her mate's residence after marriage. To test this hypothesis, we compare mtDNA and Y-chromosome variation in three matrilocal (in which the man moves to his mate's residence after marriage) and three patrilocal groups among the hill tribes of northern Thailand. Genetic diversity in these groups shows a striking correlation with residence pattern, supporting the role of sex-specific migration in influencing human genetic variation.
