Genetic Identification of Eggs Purportedly From the Extinct Labrador Duck (Camptorhynchus Labradorius)
Abstract Material extracted from inside the shells of nine purported Labrador Duck (Camptorhynchus labradorius) eggs was subjected to DNA extraction and polymerase chain reaction (PCR) amplification. For each egg, partial sequences of one to three mitochondrial genes (12S, ND2, and control region) w...
