dc.descriptionThe cytogenetic study of 182 river buffalo (Bubalus bubalis L., 2n = 50) of Murrah, Mediterranean and Jaffarabadi breeds, from the State of São Paulo, was carried out to characterize their chromosomes and to detect possible chromosomal abnormalities. The karyotypes were indistinguishable with conventional staining as well as with C and replication R banding techniques. In about 44% of the sample (8 males and 72 females), an X marker chromosome due to a fragile site was shown. The frequency of metaphases expressing the fragility site on the X was highly variable, from 2.86 to 41.03%. In females, the fragile site, rarely appeared on both X chromosomes. Most of the metaphases showed only 1 marker chromosome. In R-banded metaphases using 5-bromodeoxyuridine (BrdU) treatment, it corresponded in general to the late replicating X chromosome. No correlation between the X fragile site and altered phenotype was found. Structural and numerical chromosome rearrangements were ruled out in the present sample of buffalo.
