Since gene and trait are two intertwined terms used in genetics but not the same, we must be very clear with the difference between gene and trait. Briefly, genes have the information, which determines the formation of proteins in the body. These proteins ultimately design the structure of all organisms. Thus, genes determine the characteristics (traits) of all organisms. This is the key difference between gene and trait, but the main focus of this article to elaborate more on the difference between gene and trait while explaining the individual terms sufficiently.
Gregor Mendel was the first person to describe the existence of genes and their inheritance patterns
