Swollen areas present on the prophase-I chromosomes are called chromatin.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question states that swollen areas present on the prophase-I chromosomes are called chromatin. We need to analyze whether this statement is true or false.

2. **Identifying Prophase I Characteristics**: During prophase I of meiosis, chromosomes undergo a process called condensation. This means that the long, thin strands of chromatin (the uncoiled form of DNA) become tightly packed into short, thick structures known as chromosomes.

3. **Clarifying Chromatin vs. Nucleosomes**: The term "chromatin" refers to the material that makes up chromosomes, which includes DNA and proteins. However, the swollen areas referred to in the question are not called chromatin. Instead, these areas are known as nucleosomes.
