Brief description We aim to compare mutational events between microsatellite loci that vary in their exposure to recombination. We are able to do this because of a remarkable finding that Australian brushtail possums have multiple occurrences of a single microsatellite repeat element within the Y-chromosome and among autosomal loci. We will compare variation between the Y-linked and non Y-linked loci within and among individual possums and use those comparisons to distinguish between recombinant and non- recombinant mutational mechanisms. These data will provide new insights into the mutational mechanisms that drive variation in these most important molecular markers.
