1. Gamete Size Difference:

One of the key characteristics of anisogamy is the difference in size between the two types of gametes produced by individuals of different sexes or genders.

2. Role of Male and Female:

In anisogamy, one type of individual typically produces larger, immobile gametes referred to as eggs or ova, while the other produces smaller, motile gametes known as sperm.

3. Reproductive Investment:

Anisogamy also involves a difference in the amount of energy and resources invested by each sex or gender in gamete production and parental care.

4. Evolutionary Advantages:

The existence of anisogamy is believed to have evolutionary advantages, as it allows for increased genetic variation and the adaptation to changing environments.

5. Common in Many Species:

Anisogamy is a prevalent form of sexual reproduction strategy observed in various organisms, including plants, animals, and protists.
