When two genes are located close together on the same chromosome, they are most likely to show:
Correct answer: C. Genetic linkage
- A. Complete dominance
- B. Independent assortment
- C. Genetic linkage
- D. Random mutation
Explanation
Genes positioned close together on one chromosome tend to be inherited together, a phenomenon called genetic linkage. Crossing over can separate them, but the separation frequency is generally low when the genes are close.
