Introduction to Experimental Genetics

Abstract

Variability in observed phenotypes may result from a variety of factors — inherited as well as environmental. The blend of all these influences gives rise to the unique being every living creature is. Still, the main role of science is to identify the rules which unite seemingly unrelated phenomena. The role of genetics is no different. Its first, and most important, task is to identify the major factors that give rise to different phenotypical characteristics. Once these major factors have been identified, the investigation can be carried on in order to identify genes having secondary effects.
