Which statement correctly describes oviducts in poultry compared with most mammals?

• A. Mammals have a single oviduct.
• B. Birds have no oviducts.
• C. Poultry have one oviduct.
• D. All animals have multiple oviducts.

Answer: (C)

In birds, including poultry, only one oviduct is functional. It runs from the ovary to the cloaca, with the right oviduct usually vestigial and nonfunctional. The left oviduct is a long, specialized tube that adds albumen, membranes, and the shell to the developing egg as it passes along. In contrast, most mammals have two oviducts—one on each side—leading to the uterus. Because poultry rely on a single functional oviduct, the statement that poultry have one oviduct is correct.
