What major contribution did Barbara McClintock and Harriet Creighton make to the study of recombination?

Solution

Barbara McClintock and Harriet Creighton provided a genuine demonstration that recombination of genes linked on the chromosome required a physical exchange of segments of its chromosome with a homologous partner. They studied linkage in the corn.

They followed the knob which was present on the specific chromosome of corn and corelated the physical structure to its specific phenotypes.

McClintock was the first among the category to receive an unshared nobel award for her discovery of genetic transposition in 1983
