Abstract: | G- and R banded cattle (Bos taurus L.) karyotypes at about 500 band level are reported and discussed in light of chromosome banding standard nomenclature discrepancies. GTG-, GBG-, RBA- and RBG-banded karyotypes were arranged according to the Reading Conference standard. The G- and R-banding patterns of small acrocentric and disputed chromosomes (25, 27, 28 and 29) are demonstrated using some bovid marker chromosomes. G- and R-banded ideogrammatic representations using only one common banding nomenclature were also performed. This study is a contribution to the construction of new and clearer standard G- and R-banded karyotypes for this important species.accepted for publication by H. C. Macgregor |
