Solution

The correct option is B

Sutton and Boveri


Walter Sutton and Theodor Boveri proposed the chromosome theory of inheritance (i.e, chromosomes are physical basis of heredity) after observing that the behaviour of chromosomes was parallel to the behaviour of genes predicted by Mendel. Watson and Crick proposed the double helical model of DNA. The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. Mendel is called the father of genetics. He performed hybridisation experiments on garden pea and proposed laws of inheritance. Morgan coined the term linkage.
