Identification of an autosome to X chromosome translocation in the domestic cow
1992
Gallagher, D.S. Jr | Basrur, P.K. | Womack, J.E.
Chromosomes were harvested from two fibroblast lines derived from a phenotypically normal cow and her albino daughter, both known to be heterozygous for an X/autosome translocation. QFH-banding after early BrdU incorporation identified the translocated autosomal material as chromosome 23 bands 13-25, and revealed that the centromeric portion of the translocated chromosome 23 had been retained. Fluorescent in situ hybridization of a BoLA Class I cDNA probe to the normal chromosome 23 and to the translocated autosomal material confirmed the identity of the translocation, and allowed a more precise sublocalization of the MHC in cattle than that previously reported.
