Frequency of recombination between gene pairs on same chromosome as a measure of the distance between genes to map their position on chromosome, was used for the first time by
Sutton and Boveri
Alfred Sturtevant
Henking
Thomas Hunt Morgan
Alfred Sturtevant was the first to propose and use the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes. This concept laid the foundation for genetic mapping, and his work was performed in collaboration with Thomas Hunt Morgan's laboratory.
Therefore, The correct option is (B): Alfred Sturtevant
Recombinant DNA technology is the process used for producing new genetic combinations by joining different genetic material (DNA) together and inserting them into host organisms from two different species or sources. These new combinations are of value to medicine, science, industry, and agriculture.
Step 1- Isolation of Genetic Material.
Step 2- Cutting the gene at the recognition sites.
Step 3- Amplifying the gene copies through Polymerase chain reaction ( PCR)
Step 4- Ligation of DNA Molecules.
Step 5- Insertion of Recombinant DNA into Host.
