Expert Solution
Step 1

DNA is the genetic material in most living organisms. It is the information hub of the cell that contains instructions for the synthesis of proteins. DNA contains inheritable segments that are called genes that contain instructions for protein synthesis. These genes when expressed in an organism give a characteristic phenotype. Each gene is governed by two alleles that produce contrasting phenotypic effects upon expression.
