Chapter 17, Problem 7TY
Summary Introduction
Introduction: A gene is defined as the functional unit of a chromosome that codes for a particular protein. Genes are also called hereditory units as these are responsible for transferring genetic information from one generation to other generation. A gene can code for proteins that affect a single function or trait or it can also code for a protein that affect multiple traits.
