The genes dumpy wings (dp), clot eyes (cl), and apterous wings (ap) are linked on chromosome II of Drosophila. In a series of two-point mapping crosses, the genetic distances shown below were determined. What is the sequence of the three genes?
a. dp-ap 42
b. dp-cl 3
c. ap-cl 39

Answer 1

Answer: dp---cl------------ap

Explanation:

dp-----------42-----------ap

dp---3---cl
