Metaphase chromosomes from cultured lymphocytes were prepared from 246 bulls including Bos indicus, Bos taurus, Bos (Bibos) banteng , Sanga and interspecific and intra‐specific breed crosses. Morphology and karyotype position of the Y chromosome for each bull were noted. Karyotype position of the Y chromosome varied between bulls from 25th to 29th pair and the Y chromosomes of Bos indicus and breeds derived from Bos indicus bulls were acrocentric while those of Bos taurus , Sanga and breeds derived from these bulls were metacentric/submetacentric. Two forms of Y chromosome were noted In the Droughtmaster breed. C‐banding patterns of the acrocentric Y chromosome were characteristic and enabled easy identification.
