[Centromere staining in ten species of ruminants by C and R banding techniques]

The centromeric regions of acrocentric or telocentric chromosomes of 10 species of the order Artiodactyla, suborder Ruminantia, have shown to be equally deeply stained either with the C-banding or the R-banding technique. These unusual staining properties could be linked with the presence of a particular type of chromatin. The importance of centromeric fusions linked with speciation in the Bovoidea is recalled.
