A Simple And Improved Pcr-Based Technique For White-Tailed Deer (Odocoileus Virginianus) Sex Identification, Alec R. Lindsay Ph. D., Jerrold L. Belant

We describe a simple single-reaction technique for identifying the sex of white-tailed deer (Odocoileus virginianus) based on the PCR amplification of a zinc-finger intron using one pair of primers. Although Sry-coamplification confirmed sex identities, use of the Sry marker was unnecessary due to dimorphic alleles on the X and Y chromosomes at the zinc-finger locus. Insertions in intron 7 of the Y-linked allele (417 bp) make it nearly twice as long as the X-linked allele (236 bp) and thus the amplification products are easily discernable by simple agarose gel electrophoresis. The relatively short size of these products makes them useful …
