Summary Introduction
Concept introduction: The term “master regulator gene” was coined by Susumu Ohno over 30 years ago. The development of an organism from a fertilized egg from its embryonic stage to adulthood requires the synchronized expression of sets of genes at the right times and in the proper places. Master regulator genes are the sets of genes that are responsible for the expression of normal body features of an adult one.
