In a mapping cross, you determine that the recombination frequency between: loci Q and P is 12%
Loci Q and L is 15%.
If locus Q is in between loci P and L, then the recombination frequency between P and L should be approximately
A) 3%.
B) 27%.
C) 50%.
D) 75%.

Question

Quizplus · Accepted Answer

If Q is in between P and L, then the distance between P and L must be the sum of the recombination frequencies between each locus and Q, which is (12% + 15%) = 27%. Therefore, the recombination frequency between P and L should be approximately 27%.
