Random amplified polymorphic DNA (RAPD) fingerprinting was carried out to investigate the sex-specific DNA sequence for sexing in Taiwan water buffalos. One hundred and forty random primers were used for RAPD-PCR (polymerase chain reaction). One of these primers, OPC-16, produced a 321 bp fragment found only in tested males. This male-specific fragment was isolated and constructed into plasmids for nucleotide sequencing, a novel male-specific sequence was obtained. Two primers (BuSexOPC16-F and -R) were designed according to the cloned male-specific sequence to amplify the male-specific fragment using PCR for sexing. Sex-specific bands in the gel were represented in the males but none were found in the females when the Taiwan water buffalo genomic DNA samples were amplified with these two primers using PCR. The same results were also obtained from Taiwan yellow, Holstein, Angus, and Hereford cattle samples. This showed that the sex of these five breeds could be easily and effectively determined using the PCR technique. (c) 2004 Elsevier Inc. All rights reserved.
