Quantitative genetics: A promising approach for the assessment of genetic variation in endangered species

Abstract

The measurement of genetic variation is often an important component of endangered species management programs. Each of several tools available to measure genetic diversity has positive and negative attributes. Quantitative genetic techniques have not received much attention in the conservation field, yet they are likely to reveal variation that is most closely associated with components of fitness. In addition, quantitative genetics may not be as logistically difficult for threatened populations as was once thought. Finally, quantitative genetic models provide a better outlook for conservation programs than single-locus models.
