Sutton and Boveri

Answer 2

Chromosomal Theory of Inheritance believes that chromosomes are vehicles of hereditary information which possess Mendelian factors or genes and it is the chromosomes which segregate and assort independently during transmission from one generation to the next. Chromosomal theory of inheritance was proposed by Walter Sutton and Theodore Boveri independently in $1902$. But it was later modified and expanded by Morgan, Sturtevant and Bridges.
