Two genes that are 8.2 map units apart will have a recombination frequency of:

Question

Quizplus · Accepted Answer

The recombination frequency is the percentage of recombinant offspring in a cross. The formula to calculate recombination frequency is:

Recombination frequency = (# of recombinant offspring / total # of offspring) x 100%

Since the two genes are 8.2 map units apart, we can assume that they are on the same chromosome, but far enough apart that they are likely to undergo at least one crossover event during meiosis. The maximum recombination frequency for two genes that are located on the same chromosome is 50%. This occurs when the genes are located at opposite ends of the chromosome and there is no interference.

Using the formula above, we can solve for the recombination frequency:

Recombination frequency = (0.082) x 100% = 8.2%

Therefore, the best choice is C, which corresponds to 8.2%.
