He determined that some genes are linked (you will get one if the other is present).
|
|
|
He determined that all genes are unlinked (you will never get certain genes because you have another).
|
|
|
He discovered what genes were.
|
|
|
He studied peas and determined that flower color was linked to plant height.

Detailed explanation-1: -Therefore, Morgan correctly proposed that the strength of linkage between two genes depends upon the distance between the genes on the chromosome. This proposition became the basis for construction of the earliest maps of the human genome.
Detailed explanation-2: -Morgan discovered a mutation that affected fly eye color. He observed that the mutation was inherited differently by male and female flies. Based on the inheritance pattern, Morgan concluded that the eye color gene must be located on the X chromosome.
Detailed explanation-3: -Thomas Hunt Morgan was awarded the Nobel Prize in Physiology or Medicine in 1933. The work for which the prize was awarded was completed over a 17-year period at Columbia University, commencing in 1910 with his discovery of the white-eyed mutation in the fruit fly, Drosophila. Morgan received his Ph. D.
