One half of a duplicated chromosome is referred to as a chromatid. During cell division, when a chromosome is duplicated, it consists of two identical halves that are connected at a region called the centromere. Each of these halves is known as a chromatid.

This term is essential to understand during the phases of cell division, particularly in mitosis and meiosis, where the separation of sister chromatids leads to the distribution of genetic material to daughter cells. Chromatid emphasizes the relationship and identity of the duplicated components of a chromosome before they are separated.
