In a genetic study,researchers find that two genes show the expected linkage in 170 subjects,while 30 subjects show traits that indicate crossing over has occurred.What is the distance between these genes?
A) 5 cM
B) 10 cM
C) 15 cM
D) 20 cM
E) 25 cM

Question

Quizplus · Accepted Answer

The distance between the two genes can be calculated using the formula:
(Distance in cM = (Number of recombinants / Total number of offspring) x 100)
Given, 30 subjects show traits indicating crossing over and a total of 200 (170 + 30) individuals were studied.
Therefore, distance = (30/200) x 100 = 15 cM.
