Abstract

A systematic approach for finding regions of the genome that are important in the control of productive traits has only recently become available. The advent of microsatellite markers for sheep and other domestic ani- mals (Crawford et al. 1991) and their subsequent place- ment on linkage maps (Crawford eta/. 1995, Kappa et al 1997) has provided a set of highly informative markers densely spread across the genome. With these reagents we now have the ability to follow the inheritance of each region of every chromosome in any cross. Providing we have pedigrees in which genes which have an important influence on the trait of interest are segregating, we can systematically identify the regions of the genome in- volved. This process has become known as the genomic scan.
