Ostrich absence of heteromorphic sex chromosomes, unique sequences or markers located in the ostrich W-chromosome. Random amplified polymorphic DNA (RAPD) fingerprinting was carried out to investigate the sex-specific DNA sequence for sexing in ostrich. One hundred and forty random primers were used for random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR). One of these primers, OPAJ-13, produced a sex-specific band only found in tested females, which was isolated and constructed into plasmids for nucleotide sequencing. A 760 bp novel female-specific sequence was obtained. Two primers (OstSexOPAJ13-F and -R) were designed according to the cloned female sequence to amplify the female-specific fragment from genomic DNA of ostriches for sexing by PCR. The sex-specific band was represented in females but none were found in the males. This result showed that the sex of ostrich could be easily and effectively identified using the female-specific primers for PCR technique. (c) 2006 Elsevier Ltd. All rights reserved.
