Cross over values (COV’s) can be considered as the relative distance between genes and are used to help construct chromosome maps. Four genes, called P, Q, R and S, are found on the same chromosome. Use the following COV’s to work out the sequence of the four genes. P to Q = 33 Q to R = 8 R to S = 15 P to S = 10 P to R = 25 The sequence of the genes is
