The recombination that occurs during meiosis (in heterozygotes) generates data that are a useful tool for making linkage maps. The Chromosome Theory of Heredity. Mutations. Regulation of Gene Expression. Objectives. State the chromosome theory of heredity. Explain how gene linkage affects inherited traits.
