What is the difference between Blood and Feather sexing?
Feather sexing and blood sexing are in most ways identical. Both procedures require small amounts of template DNA (DNA isolated from each sample). Both use an assay procedure known as PCR. Both, in many cases, require the use of enzymes to break down the final PCR product before it is run through an electroforitic gel. Finally, both are analyzed using photographs and computer scans, and the final results are identical. Experience and know-how are vital when performing any of these assays, as well as when determining the final outcome. For example, an identical PCR assay can be performed by several different individuals or labs with varying levels of success. Some would then say that the assay is not reliable, while others might argue that it’s not the assay that should be in question, but rather the individuals doing the testing. Is feather sexing as accurate as blood sexing? YES, using our protocols we have not been able to detect any difference in the accuracy rates of blood and feat
