Which scientists are associated with the Chromosomal Theory of Inheritance?

• A. Mendel and Boveri
• B. Watson and Crick
• C. Morgan and fellow scientists
• D. Hershey and Chase

Answer: (C)

The Chromosomal Theory of Inheritance states that genes reside on chromosomes and that their inheritance follows the behavior of chromosomes during meiosis. The best association here is Morgan and fellow scientists, because Morgan’s group used fruit flies to provide direct evidence that a gene could be linked to a specific chromosome, demonstrated sex-linked inheritance, and showed that recombination could break linkage to create new combinations. These experiments tied Mendelian inheritance to the physical behavior of chromosomes and led to gene mapping, solidifying the idea that chromosomes are the carriers of genes. While Mendel established the basic rules of inheritance and Boveri helped articulate the theory, Morgan and his collaborators gave the crucial experimental proof in a living organism.
