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