Which outcome occurs when a songbird's syrinx possesses asymmetrical labia?

💡 Explanation

Vocal complexity arises from the independent control of each labium within the syrinx during vocalization. Asymmetrical labia directly affects independent control; therefore more complex song is achieved rather than simpler songs.
