Abstract

A G- and R-banding comparison of cattle (Bos taurus, 2n = 60), goat (Capra hircus, 2n = 60) and sheep (Ovis aries, 2n = 54) chromosomes at the 450 band level was made. The study revealed a large number of banding homologies among the autosomes of the three species and resolved some ambiguities in arranging some of their small disputed acrocentrics by direct and indirect comparisons with some bovid marker chromosomes. A loss of the subcentromeric G-positive band in sheep chromosome 2g was observed when the G-banding patterns of sheep 2q and homologous cattle and goat chromosome 2 were compared. The chromosomal divergences among cattle, goat and river buffalo (Bubalus bubalis, 2n = 50) sex chromosomes are shown to have occurred by pericentric and paracentric inversions with a loss (or acquisition of constitutive heterochromatin.
