摘要：Grivet monkey populations in central Ethiopia showed a homogeneous distribution of nuclear variations but differentiated distribution in mtDNA. To explain this difference in gene distribution patterns, I examined the effect of male migration on homogenized nuclear variations among populations. If isolation inducing mtDNA differentiation occurred in both sexes, male migration is assumed to have homogenized nuclear gene distribution after isolation, because of female philopatry. Under this assumption, the time required for homogenization is obtained by computer simulation using a migration rate calculated from distribution of nuclear variation under the two-dimensional stepping stone model. The computer simulation indicates that at most 105 years is enough to homogenize nuclear variation via male migration.
