The map distance between the genes A and B is 3 units, between B and C is 10 units and between C and A is 7 units. The order of the genes in a linkage map constructed on the above data would perhaps be

A, B, C

A, C, B

B, C, A

B, A, C

Solution

B, A, C

From the recombination frequencies between different genes A, B and C, it is clear that distance between A and B genes is 3 units between B and C is 10 units and C and A is 7 units. Hence, linear order of genes on chromosomes is
