What is anisogamy?

Anisogamy is the fusion of two gametes that are different in size or form.

In anisogamy, the male gamete is usually small and motile (like sperm), while the female gamete is large and non-motile (like egg). This type of reproduction is common in humans, animals, and many plants. It is different from isogamy, where gametes are similar in size and shape.

Examples:

• Humans (sperm and egg fusion)
• Many algae and fungi
• Animals like frogs and fish
