Percentage of recombination between A and B is 9 %, ~A and C is 17 %, ~B and C is 26 % , then the arrangement of genes is

Step-by-step solution

1 map unit or centimorgan is equivalent to 1 % recombination between two genes. The frequency of recombination can be used to depict the arrangement of the genes. Recombination frequency between three genes is A - B =9 %, ~A - C =17 % and B-C=26 % By manipulating the three possibilities of their arrangements it can be concluded that the three genes must be arranged in the order B - A - C with distance between B - A being 9 ~cm , ~A - C being 17 ~cm and B - C being 26 ~cm .
