Five bovine polymorphic dinucleotide microsatellite loci (DIK008, DIK010, DIK015, DIK016 and DIK020)

Construction of YAC/BAC contig map for the BTA 6q21 region containing a locus for bovine chondrodysplastic dwarfism

To characterize the bovine chromosome 6q21 for bovine chondrodysplastic dwarfism (BCD), we developed 48 new microsatellite markers from yeast artificial chromosome (YAC) and bacterial artificial chromosome (BAC) clones using a modified magnetic bead capture method. These new markers were used to construct a high-resolution physical map of the region with a total of 85 loci. The physical map will be a powerful tool for successful positional cloning experiments.

Characterization of 42 highly polymorphic bovine microsatellite markers

We have isolated 42 highly polymorphic microsatellite (GT/CA)n markers from Japanese black cattle Wagyu (Bos taurus). Forty-one of the markers were assigned to bovine autosomes with lod scores > 6, through linkage analyses performed on the International Bovine Reference Family Panel (IBRP). The remaining marker showed X-linked inheritance. These markers exhibited an average heterozygosity value of 0.67 with between four and 17 alleles on the IBRP.
