Abstract

Recent studies in the literature have appliedphylogenetic methods based on genetic distancesto set priorities for conservation of domesticanimal breeds. While these methods may beappropriate for between-species conservation,they are clearly inappropriate forwithin-species breed conservation, because theyignore within-breed variation. In this paper weshow the basic tools to analyse geneticdiversity in subdivided populations withinspecies, and illustrate the errors incurred byapplying methods based exclusively on geneticdistances. We also show that maximisation ofgenetic diversity (minimisation of coancestryor kinship) is equivalent to maximisation ofeffective population size, as in undividedpopulations, and derive a generalisation ofprevious equations for the prediction ofeffective size. Finally, we discuss thestrategies for conservation in the light of thetheory.
