Chronologically arrange the names of scientists who contributed to the study of genetics.
(A) Alfred Sturtevant
(B) Gregor Mendel
(C) Thomas Hunt Morgan
(D) Sutton and Boveri
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (B), (D), (C), (A)
(B) Gregor Mendel — first. He did his hybridisation experiments on garden peas (1856–1863) and gave the laws of inheritance.
(D) Sutton and Boveri — second. In 1902 they noted that chromosomes pair and separate like Mendel’s factors, and Sutton united the two ideas as the chromosomal theory of inheritance.
(C) Thomas Hunt Morgan — third. Working on Drosophila, he gave the experimental proof of the chromosomal theory and the ideas of linkage and recombination.
(A) Alfred Sturtevant — last. Morgan’s student, he used recombination frequencies to map the position of genes on a chromosome.
