Solution

The correct option is C Bateson and Punnett
Mendel put forward his findings and then other scientists started research on other related fields and gradually new discoveries kept on adding in the 20th century. In early 1900s, William Bateson and R.C. Punnett, while working on the inheritance pattern of sweet pea (Lathyrus odoratus) were fascinated with the findings which deviated from Mendel's laws, specifically with the independent assortment of alleles and eventually discovered linkage. The inheritance of two characters from the parent generation to the F2 generation is not always assorted independently but also gets coupled. After performing crosses, they saw not all the crosses yielded show similar results with the Mendelian result, some phenotypes appear far frequent than the Mendelian genetics. On the basis of these findings they extended the research and proposed that some alleles get coupled with one another, not all assort independently, which later got named as Linkage.
G.J. Mendel who performed experiments on around 28000 pea plants of 14 varieties in eight years the laws of inheritance, which remained unnoticed for 34 years and was rediscovered after almost 34 years by three different scientists working independently.
T.H. Morgan an American scientist who demonstrated that genes are carried on chromosomes and are the mechanical basis of heredity.
