The frequency of recombination between gene pairs on the same chromosome as a measure of the distance gene was explained by:

Options

  1. AT.H. Morgan
  2. BGregor J. Mendel
  3. CAlfred Sturtevant
  4. DSutton Boveri

Correct answer

C. Alfred Sturtevant

Step-by-step solution

Alfred Sturtevant (student of Morgan) used the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes and ‘mapped’ their position on the chromosome. Two genes show higher frequency of crossing over if the distance between them is higher and lower frequency if the distance is small.
