Q.

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:

  1. A

    Thomas Hunt Morgan

  2. B

    Sutton and Boveri

  3. C

    Alfred Sturtevant

  4. D

    Henking

Solution

Alfred Sturtevant — then an undergraduate in Morgan's lab — first used recombination frequencies between linked genes as a proxy for physical distance, producing the first genetic linkage map. Morgan provided the framework of linkage; Sutton and Boveri proposed the chromosomal theory of inheritance; Henking discovered the X chromosome.
