Q. The recombination frequency between the genes a & c is 5%, b & c is 15%, b & d is 9%, a & b is 20%, c & d is 24% and a & d is 29%. What will be the sequence of these genes on a linear chromosome?
A) a, c, b, d
B) a, d, b, c
C) d, b, a, c
D) a, b, c, d
Explanation
[Solution] a-c = 5, c-b = 15, b-d = 9 add up to a-b = 20, c-d = 24 and a-d = 29, so the order is a, c, b, d. Answer (1).
