The correct option is C Bateson and Punnett
When two or more genes on a chromosome staying together and inherited through generations without separation are called linkage. In 1902-1903 linkage suggested by Sutton and Boveri. Linkage was first studied by Bateson and Punnet in 1906. The linkage between genes was discovered in sweet pea experiments. In 1910 Morgan who clearly proved linkage theory in fruit fly experiments. Thus, the correct answer is C.
