Description

<jats:title>Abstract</jats:title><jats:p>Dominant markers such as amplified fragment length polymorphisms (AFLPs) provide an economical way of surveying variation at many loci. However, the uncertainty about the underlying genotypes presents a problem for statistical analysis. Similarly, the presence of null alleles and the limitations of genotype calling in polyploids mean that many conventional analysis methods are invalid for many organisms. Here we present a simple approach for accounting for genotypic ambiguity in studies of population structure and apply it to AFLP data from whitefish. The approach is implemented in the program <jats:sc>structure</jats:sc> version <jats:italic>2.2,</jats:italic> which is available from <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://pritch.bsd.uchicago.edu/structure.html">http://pritch.bsd.uchicago.edu/structure.html</jats:ext-link>.</jats:p>
