The first task of genetics was to determine the laws which govern the transmission of characters from parent to offspring and to locate the material basis for this regular behavior. The task was quickly accomplished so that 20 years ago the gene-chromosome theory of heredity was well established; it has since been the ABC of genetics and provides the framework upon which more recent work rests. The substance of the theory, as you will recall, is that the characters observed in an adult individual are determined by genes which are arranged in a linear order in the chromosomes.
