Question

Female reproductive system of the birds is characterised by

• A. Paired ovaries functioning alternatively
• B. Left functional ovary
• C. Right functional ovary
• D. Equipotent left and right ovaries

Answer 1

The correct option is B Left functional ovary

In the majority of the avian species, only the left ovary is functional. Although the right one is present embryologically, it regresses during development and is vestigial in the adult bird.
Thus, the correct answer is (B), Left functional ovary.
