Chronological Arrangement
The correct sequence is based on the approximate time of their key work in the field of genetics:
|
Scientist |
Contribution |
Approximate Time Frame |
Sequence |
|
(B) Gregor Mendel |
Discovery of the basic laws of inheritance (Mendelism) through pea plant experiments. |
1856–1863 (Published in 1865) |
1st |
|
(D) Sutton and Boveri |
Independently proposed the Chromosomal Theory of Inheritance, linking Mendel's "factors" to chromosome behavior during meiosis. |
1902–1903 |
2nd |
|
(C) Thomas Hunt Morgan |
Provided experimental proof for the Chromosomal Theory using Drosophila (fruit flies), discovering sex-linked inheritance. |
Started around 1910 |
3rd |
|
(A) Alfred Sturtevant |
A student in Morgan's lab, he created the first gene map by using recombination frequencies to determine the linear arrangement of genes on a chromosome. |
1913 |
4th |
