| Popis: | The ability to identify the sex of embryo and control of sex ratio has a great commercial importance to livestock industry. Prediction of embryonic sex could be useful in the management decisions of sex selection in breeding programs. Several methods have been attempted to determine the sex but the polymerase chain reaction (PCR)-based sexing method is generally favoured, as it is cost effective, simple and reliable. The aim of the present study was to identify sex of sheep embryos produced in vitro through amplification of glyceraldehyde 3-phosphate dehydrogenase (GAPDH), sex-determining region Y (SRY) and amelogenin genes present in genomic DNA (gDNA) of embryos through PCR. To avoid false interpretation of the result by no amplification of SRY in female embryos, a duplex PCR was approached to amplify combinedly SRY and GAPDH genes. Sex-specific blood was used in PCR as positive control. In vitro sheep embryos were produced as per standardized protocol of laboratory. Sexing of sex-specific blood and in vitro produced embryos were approached though PCR to amplify the respective genes using gDNA present in the sample without its traditional isolation. The accuracy of sex prediction for embryos was 100% by this procedure. |
