👉 The term "chromogen" is a scientific term used in the field of biochemistry and genetics. In simpler terms, it refers to a type of molecule that contains genetic information encoded by DNA. Chromosomes are the primary building blocks of all living organisms, including humans, and they contain the genetic material for most traits such as height, weight, and eye color. Chromogen is crucial in understanding how our genes influence each other and how different genes interact with each other in a complex manner.
