How population size influences quantitative genetic variation and differentiation among natural, fragmented populations remains unresolved. Small, isolated populations might occupy poor quality habitats and lose genetic variation more rapidly due to genetic drift than large populations. Genetic drif...

How population size influences quantitative genetic variation and differentiation among natural, fragmented populations remains unresolved.
