Solution
Correct 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.
This easy difficulty biology question is from the chapter principles of inheritance and variation, covering the topic of gene mapping. It appeared in the 2025 exam.
