Solutions For An Introduction to Genetic Analysis Chapter 4 Problem 54P

For the RF of 10%:

This value is multiplied by 50% to get a corrected map distance of 11.15%.

For the RF of 20%:

This value is multiplied by 50% to get a corrected map distance of 25.5%.

For the RF of 30%:

This value is multiplied by 50% to get a corrected map distance of 45.8%.

For the RF of 40%:

This value is multiplied by 50% to get a corrected map distance of 80.4%.

A graph of the data would be:

When map distances are small, the observed and corrected frequencies are almost the same. Hence, the larger the RF value, the more important it is to correct the underestimation of map distance by using the mapping function.
