Question

Who used in frequency of recombination between gene pairs on the same chromosome as a measure of distance between genes and mapped their position on chromosome.

• A. Alfred Sturtevant
• B. Gregor Mendel
• C. Correns
• D. Tschermak
• E. Watson and Crick

Answer 1

The correct option is A Alfred Sturtevant

Alfred H Sturtevant, one of Morgans students, used the frequency of recombination or percentage of crossing over between gene pairs on the same chromosome as a measure of the distance between genes and mapped their position on the chromosome. This technique is based on the assumption that the farther apart two genes are on a chromosome, the higher the probability that a cross over will occur between them.

So, the correct answer is 'Alfred Sturtevant'.
