Abstract

The burgeoning knowledge associated with the gene maps of humans and mice can provide key information for the identification of genes underlying production traits in livestock. In tbeo~~, it should be possible to tramlate information associated with a human chromosomal location to a chromosome location in sheep, cat& or deer. However, in practice, livestock gene maps often require more comparative links to make accurate &anslation possible. We have taken a novel approach to livestock comparative mapping by using an interspecies hybrid mapping panel to map both gene loci and sheep and cattle microsatellites. The panel comprises DNA from 346 l/4 Pere David’s deer (Ekxphurus dnvidinnuj 3/4 red deer (Cervus elaphur) backcross progeny of male FI P&e David’s deer x red deer hybrids. We are using this deer mapping resource to relate the sheep, cattle and human gene maps and by mapping key markers from each.
