  How are chromatin, chromatid and chromosomes related to each other?

Answer:

  Inside the nucleoplasm a tangled mass of thread-like structures is called chromatin. They are formed of an acid called Deoxyribonucleic Acid (DNA) and proteins. When a cell starts to  divide, the tangled mass of chromatin condense into long threads and finally rod-like bodies called chromosomes. The    chromosomes contain stretches of DNA which carry information  for protein synthesis.                                               A gene is called the hereditary unit and DMA is called the hereditary material,                                                A chromatic is one copy of duplicated chromosome which is generally joined to the other copy by a centromere.
