There are three genes a, b, c. Percentage of crossing over between a and b is 20%, b and c is 28% and a and c is 8%. What is the sequence of genes on chromosome?
View answer and explanation
Correct option: A
b, a, c
Option A (b, a, c) is correct because the gene sequence is determined by the percentage of crossing over, with the largest percentage between the farthest genes. Therefore, 'b' and 'c' are farthest apart, and 'a' lies in between.
