摘要
The use of the in vivo 5-bromodeoxyuridine (BrdU) incorporation technique made it possible to induce highly reproducible replication bands of the RBA type in two species of the order Cypriniformes (Teleostei), Rutilus rutilus and Scardinius erythrophthalmus. This allowed unequivocal identification of each individual chromosome by its banding pattern and the preparation of species specific karyotypes. Comparison of RBA-banded karyotypes of these two closely related fish species revealed that the majority of the chromosomes could be homoeologized either directly, or by assuming paracentric or pericentric inversions.
