Which statement correctly describes poultry oviducts in relation to mammals?

• A. Mammals have a single oviduct.
• B. Birds do not have oviducts.
• C. Poultry have one oviduct.
• D. All animals have one oviduct.

Answer: (C)

In birds, the egg travels through one functional oviduct that runs from the ovary to the cloaca, with the right side typically absent or vestigial. This means poultry have a single oviduct. Mammals, by contrast, have two oviducts (fallopian tubes), one on each side, connecting each ovary to the uterus. So the statements that mammals have a single oviduct, that birds lack oviducts, or that all animals have one oviduct aren’t accurate. The single functional oviduct in poultry reflects how their eggs develop and are laid along one continuous duct.
