Morgan called the gene responsible for eye color the white gene, because a mutation destroying its function gives white eyes. This theory is also called the Boveri-Sutton chromosome theory is a fundamental unifying theory of genetics which identifies chromosomes as the carriers of genetic material. Suppose we considered the inheritance of three different chromosome pair, in a mating of two triple heterozygotes AaBbCc x AaBbCc. Because X and Y chromosomes look different, Bridges could see whether or not the atypical offspring had the chromosomes According to this theory, genes are carried from parents to their offspring on chromosomes.
