In genetics, a monad is a chromosome consisting of just one chromatid.
To understand this better, let's break it down:
- Chromosomes: These are structures within our cells that contain DNA. They carry our genes, which determine our traits.
- Chromatids: These are identical copies of a chromosome that are created during cell division. Think of them as sister strands.
Here's a table summarizing the difference between a monad and a dyad:
| Term | Description | Number of Chromatids |
|---|---|---|
| Monad | A chromosome consisting of one chromatid | One |
| Dyad | A chromosome consisting of two chromatids | Two |
In essence, a monad represents a single, unreplicated chromosome, while a dyad represents a chromosome that has been duplicated, consisting of two identical sister chromatids joined together. During cell division (meiosis or mitosis), dyads eventually separate into monads, ensuring each daughter cell receives the correct genetic information.
