Molecular and pedigree measures of relatedness provide similar estimates of inbreeding depression in a bottlenecked population.

Abstract excerpt

Individual-based estimates of the degree of inbreeding or parental relatedness from pedigrees provide a critical starting point for studies of inbreeding depression, but in practice wild pedigrees are difficult to obtain. Because inbreeding increases the proportion of genomewide loci that are identical by descent, inbreeding variation within populations has the potential to generate observable correlations...
