Chromosome Evolution in domestic Bovids as revealed by chromosome banding and FISH-mapping techniques.

The present review summarizes the basic cytogenetic information available pertaining to the most important Bovidae species, namely cattle, buffalo, sheep and goat, with the aim of tracing their evolutionary relationships and to provide - for the first time - the hypothetical ancestral karyotype of the Bovinae-Caprinae subfamilies, also in relation to the other nondomestic species which are included in this important taxonomic family. Evolution of the Bovinae-Caprinae autosomes and gonosomes is discussed on the basis of the most recent advances in chromosome banding, linkage studies, FISH-mapping and molecular information.
