Detecting populations in the 'ambiguous' zone: Kinship-based estimation of population structure at low genetic divergence

摘要: Identifying population structure is one of the most common and important objectives spatial analyses using genetic data. Population detected either by rejecting null hypothesis a homogenous distribution variation, or estimating low migration rates. Issues arise with current inference methods when divergence among putative populations. Low levels may be as result high ongoing historic but no current, migration. We direct attention to recent developments in use tempo-spatial closely related individuals detect estimate These 'kinship-based' approaches complement more traditional population-based providing means rates low. However, for kinship-based become widely adopted, formal estimation procedures applicable range species life histories are needed.
