What is isogamy ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Isogamy**: Isogamy is a type of sexual reproduction where the gametes involved are similar in size and shape.

2. **Characteristics of Gametes**: In isogamous reproduction, both male and female gametes are morphologically (structurally) and physiologically (functionally) identical. This means that they cannot be distinguished from one another based on their appearance or their roles in reproduction.

3. **Reproductive Process**: During isogamy, these similar gametes come together to fuse and form a zygote. Since the gametes are indistinguishable, there is no clear differentiation between male and female in this reproductive process.
