摘要：

Chromosome markers in cattle were revealed by high resolution G + C banding. In blood cultures early-BrdU incorporation together with simultaneous MTX-block was performed, as previously reported. Fluorescent G + C bands allowed us to study HC-distribution in the karyotypes of 14 Frisian, Podolian and Romagna males. The study revealed two groups of marker chromosomes. One group showed C- band heteromorphism (chromosomes 1, 11 and 27) and the other showed a more constant C-band size. In the latter group we singled out chromosomes 10, 11 and 28, from among those showing small/intermediate relative C-band size, and 1, 2, 4, 9, 13 and 26, from among those showing intermediate/large relative C-band size. © 1990 Taylor & Francis Group, LLC.
