    Abstract

    Forty autosomal type I loci earlier mapped in goat were comparatively FISH mapped on river buffalo (BBU) and sheep (OAR) chromosomes, noticeably extending the physical map in these two economically important bovids. All loci map on homoeologous chromosomes and chromosome bands, with the exception of COL9A1 mapping on BBU10 (homoeologous to cattle/goat chromosome 9) and OAR9 (homoeologous to cattle/goat chromosome 14). A FISH mapping control with COL9A1 on both cattle and goat chromosomes gave the same results as those obtained in river buffalo and sheep, respectively. Direct G- and R-banding comparisons between Bovinae (cattle and river buffalo) and Caprinae (sheep and goat) chromosomes 9 and 14 confirmed that a simple translocation of a small pericentromeric region occurred between the two chromosomes. Comparisons between physical maps obtained in river buffalo and sheep with those reported in sixteen human chromosomes revealed complex chromosome rearrangements (mainly translocations and inversions) differentiating bovids (Artiodactyls) from humans (Primates).
