What is the feature of a metacentric chromosome?

Explanation

### Step-by-Step Solution:

1. **Definition of Metacentric Chromosome**: A metacentric chromosome is a type of chromosome where the centromere is located at the middle, resulting in two arms of equal length on either side.

2. **Visual Representation**: To better understand, visualize a chromosome as an X shape. In a metacentric chromosome, the point where the two arms meet (the centromere) is at the center of the X, creating two equal halves.

3. **Characteristics**: The key feature of a metacentric chromosome is that both arms are of equal length. This symmetry is important for proper segregation during cell division.
