How are chromatin, chromatid and chromosome related to each other.

Chromatin is intertwined mass of fine thread-like structures made of DNA and protein. During cell division (mitosis or meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids. Formation of chromosomes having two similar halves or chromatids is meant for equitable distribution of chromatin which is hereditary material.
