NEET 2002 Biology question
There are three genes a, b and c. The 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
Answer: (1)
Solution
The percentage of crossing over is proportional to the distance between genes (1% = 1 map unit). The largest value is between the two outer genes, and the sum of the two smaller distances equals the largest in a linear map. Here b-c = 28%
