Question
In planogametic copulation, when one gamete (male) is smaller and motile, and the other (female) gamete is larger and non-motile, the fusion process is called:
Correct Answer
Option C is the correct answer.
Detailed Explanation
Oogamy (or heterogamy) is a type of planogametic copulation where the male gamete is smaller and motile, and the female gamete is larger and non-motile. Isogamy involves motile and morphologically similar gametes, while anisogamy involves motile gametes of different sizes.
Hint
This term is often used in broader biology for this type of gamete fusion.
