Solution

Correct Answer:

Map units

  1. Concept: Alfred Sturtevant used the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes.
  2. Unit: This distance is measured in map units.
  3. Definition: One map unit (also called a centimorgan, cM) represents a 1% probability of recombination occurring between two genes.
  4. Conclusion: Map units provide a relative measure of the position of genes on a chromosome.
