Part III is divided into “Function of Autosomes” and “Function of Sex Chromosomes.” All chromosomes that are not sex chromosomes are called autosomes. After the discussion of chromosome structure, it is important to learn some basic facts about chromosome function. Structure and function are necessarily closely related. Many structural features are the basis for the function of chromosomes. The genetic units of the chromosomes are the genes. Genes seem to function as groups and also seem to be transferred as such from generation to generation. As mentioned in Chapter 1, the first one to recognize such gene complexes was Morgan (1910b). He called them linkage groups (1911). A linkage group is the association of certain genes that are located on the same chromosome.
