Which of the following kinds of data could be used to map the relative position of three genes on a chromosome?
A) the frequencies with which the genes exhibit incomplete dominance over each other
B) the frequencies of mutations in the genes
C) the frequencies with which the genes are inherited from the mother and from the father
D) the frequencies with which the corresponding traits occur together in offspring

The frequencies with which the corresponding traits occur together in offspring could be used to map the relative position of three genes on a chromosome because if two genes are close on a chromosome, they are more likely to be inherited together and therefore their corresponding traits will occur together in offspring more frequently. This is known as genetic linkage, and the strength of the linkage between genes can be used to estimate the distance between them on the chromosome.
