Molecular genetic maps will provide insight into the genome organization and chromosomal localization of cloned genes and also a framework for the identification and localization ofmajor genes associated with economically important traits (Crittenden et al. 1993). The rapid progress being made in the development of genetic maps for humans and mice has led to a recent boom in the construction of genome maps for many farm animals. High-density linkage maps are now available for manyspecies, such as pigs, cattle, sheep, and goats. In contrast, mapping studies in avian species are much less advanced except in the chicken. To construct saturated genetic maps for more bird species, the isolation of many polymorphic genetic markers, particularly microsatellitemarkers, is a prerequisite. Although many chicken markers were available, it was difficult to screen the microsatellite marker for the duck by cross-species amplification from this species because of the poor conservation of the microsatellite sequences between the species (Huang et al. 2005).
