The identification of sex-linked loci has a theoretical and an applied value (Hurles and Jobling 2001), and sex-linked markers can be more useful than autosomal markers to address sex-specific aspects of behavioral andmolecular ecology (Erler et al. 2004). Sex-linked loci permit identifying sex in samples collected noninvasively and in species in which the sex cannot be easily determined in the field (Shaw et al. 2003), facilitate parentage analysis in species with large clutches (Walker et al. 2005), and help in confirming sex-biased dispersal and determining male effective population size (Eriksson et al. 2006). One of the first sex-linked loci identified in pinnipeds was Pvc74, amicrosatellite locus originally cloned by Coltman et al. (1996) in the harbor seal (Phoca vitulina concolor). These authors found no heterozygous males in 25 males and 10 heterozygous females in 25 females, concluding that the locus
