Detailed description of R-banded bovine chromosomes.

The detailed description of cattle chromosomes has been achieved by using the RBA technique that has been found to be faster, more reliable, and offers better resolution than either the G- or Q-banding procedures. The use of this technique for routine analysis of cattle chromosomes is, therefore, strongly recommended. The adoption of a common system of nomenclature also is desirable to avoid misclassification of chromosomes involved in structural abnormalities as well as to trace evolutionary relationships among the Bovidae.
