Abstract:
Summary Bovine BAC clones containing the 31 genes, referred to as the Texas markers used earlier to definitively assign the 31 bovine syntenic groups (U) to cattle chromosomes, were mapped by fluorescent in situ hybridization to sheep and goat R-banded chromosomes according to ISCNDB2000. All 31 markers were localized on homoeologous chromosomes and chromosome bands of the two species in agreement with previous localizations obtained both in cattle and river buffalo, definitively confirming chromosome homoeologies between Caprinae and Bovinae. In addition, we have extended physical maps of sheep and goat as 11 genes (HSD3B1, INHBA, CSN10, IGF2R, PIGR, MAP1B, DSC1, ELN, TNFRSF6, CGN1, IGF2) and 14 genes (SOD1, HSD3B1, CSN10, IGF2R, RB1, TG, PIGR, MAP1B, IGH@, LTF, DSC1, TNFRSF6, CGN1, IGF2) were assigned for the first time to goat and sheep chromosomes, respectively.Keywords: cytogenetics; goat; nomenclature; sheep; type I marker
