The polymerase chain reaction is widely used technique for the amplification of target nucleotides for the gene of interest. Amplification of the SRY gene on the Y chromosome by PCR and the identification by electrophoresis has a major role in sex determination. In the proposed method, the house keeping primer glyceraldehydes phosphate dehydrogenase (GAPDH) as a marker of both total and DNA and mitochondrial RNA and SRY gene should be used for the identification of the unknown samples. In the SDS PAGE gel electrophoresis, two bands are noticeable; first band at 218 bp for GAPDH and second band at 741 bp for SRY gene. The sex chromosomes has a important role in the etiology of normal sexual development. Biopotential gonal needs two chromosomes to the development of ovary. The existence of SRY gene located on the Y chromosome, a testis is developed. The sex ambiguity can be developed by the discodance between chromosomal sex and appearance of the external genitalies.
