Detailed explanation-1: -T. H. Morgan coined the term linkage while experimenting with fruit flies.
Detailed explanation-2: -The correct option is B T.H.Morgan. The term “linkage” was coined by T.H.Morgan.
Detailed explanation-3: -Morgan coined the term ‘recombination’ to describe the physical association of genes on a chromosome.
Detailed explanation-4: -Hint: The term linkage was coined by TH Morgan, who carried out several dihybrid crosses in Drosophila. With this, he was able to study genes that were sex-linked. He also described the physical association of genes on a chromosome.
Detailed explanation-5: -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.
