Accounting for female space sharing in St. Kilda Soay sheep (Ovis aries) results in little change in heritability estimates.

Abstract excerpt

When estimating heritability in free-living populations, it is common practice to account for common environment effects, because of their potential to generate phenotypic covariance among relatives thereby biasing heritability estimates. In quantitative genetic studies of natural populations, however, philopatry, which results in relatives being clustered in space, is rarely accounted for. The two studies that...
