| Abstract: | In this experiment, the primer pairs were designed, and polymerase chain reaction (PCR) technique to amplify the segments of the partial sex linked gene chromo-helicase-DNA-binding (CHD) to identificate pigeon's sex using feather pulps and blood.We found that two bands were demonstrated in all female egg-laying pigeons, and the sizes of them were 400 and 700 bp, respectively;In all male egg-laying pigeons, only one band appeared with length of 700 bp.100 unknown sex samples were successfully identified (52 males and 48 females).Based on the checking results between molecular electrophoresis of pigeons and the truly sex of maturity pigeons, we detected CHD gene in 2 928 early age pigeons using PCR amplification and electrophoresis in agarose gel.The PCR amplification results showed 1 517 males and 1 411 females. |
