Q. Experimental verification of the chromosomal theory of inheritance was given by :
(a) Henking
(b) Hugo de Vries
(c) Langdon Down
(d) Thomas Hunt Morgan
Solution :
Correct option : D Experimental Verification of the Chromosomal Theory of Inheritance was done by Thomas Hunt Morgan and his colleagues. He observed that the two genes under consideration in his experiments did not segregate independently as in the case of characters studied by Mendel. Morgan carried out various dihybrid crosses in Drosophila, with the genes that were sex-linked, i.e., the genes are present on the X-chromosome. So, the correct answer is ‘Thomas Hunt Morgan‘.
