Direct characterization of bovine microsatellites from cosmids: polymorphism and synteny mapping

Abstract
A (TG)8 oligonucleotide probe was used to screen 186 cosmids from a commercial bovine cosmid library. Of the 56 positive discovered, 7 were sequenced in the region of the microsatellite and analysed for polymorphism. These microsatellites, IDVGA‐2, ‐3, ‐7, ‐8, ‐9, ‐10, ‐11 showed the following number of alleles and polymorphism information content (PIC) values (7/0.616, 8/0.693, 6/0.641, 5/0.643, 2/0.239, 10/0.844, 6/0.720). The microsatellites were also assigned to synteny groups as follows: IDVGA‐2/U17, IDVGA‐3/U16, IDVGA‐7/U7, IDVGA‐8/U29, IDVGA‐9/U3, IDVGA‐10/U19, IDVGA‐11/A (probably U18).
