What is the difference between isogamous and anisogamous?
Isogamous means that those of that species produce the different size gametes while anisogamous means that those of that species produce the same size gametes.
Isogamous means that those of that species produce the same size gametes while anisogamous means that those of that species produce different size gametes.
