Reliability of photographic and molecular techniques for sexing northern bottlenose whales (Hyperoodon ampullatus)

Identifying the sex of living cetaceans can be difficult, even when species are sexually dimorphic. We compare two methods of molecular sexing (ZFY (zinc finger protein gene) and SRY (sex-determining region Y gene)) and evaluate the effectiveness of photographic techniques for identifying sex in nor...

Summary:Identifying the sex of living cetaceans can be difficult, even when species are sexually dimorphic. We compare two methods of molecular sexing (ZFY (zinc finger protein gene) and SRY (sex-determining region Y gene)) and evaluate the effectiveness of photographic techniques for identifying sex in northern bottlenose whales, Hyperoodon ampullatus, in the Gully, off Nova Scotia, Canada.
