The correct option is C Bateson and Punnett in Lathyrus odoratus
The phenomenon of physical association of 2 genes owing to their presence on the same chromosome was first discovered by Bateson and Punnett in 1906 in their experimental plant sweet pea (Lathyrus odoratus).
This phenomenon was later clearly proved and defined by Thomas Hunt Morgan through his breeding experiments on his experimental organism Drosophila melanogaster. He coined the term ‘linkage’ to explain this phenomenon.
Alfred Sturtevant was the first person to construct a genetic map.
C. elegans is another experimental model of study in genetics.
Sutton and Boveri gave the chromosomal theory of inheritance.
Hugo de Vries, Carl Correns, Eric von Tschermak were the 3 scientists responsible for the rediscovery or the resurfacing of Mendel’s work.
Pisum sativum was the plant chosen by Mendel for his experimental study.
