The maximum observable recombination frequency between two loci is generally:
Correct answer: B. 50 percent
- A. 25 percent
- B. 50 percent
- C. 75 percent
- D. 100 percent
Explanation
Unlinked loci, or loci far apart on the same chromosome, can show a maximum recombination frequency of 50 percent. A value above 50 percent cannot distinguish linkage from independent assortment.
