A0.5 centimorgans
B5 centimorgans
C50 centimorgans
D500 centimorgans
Answer & Solution
Correct answer: B. 5 centimorgans
1. Sturtevant divided his genetic map into map units called centimorgans.
2. A recombination frequency of 0.01 corresponds to 1 centimorgan.
3. A frequency of 0.05 is five times as large, so divide 0.05 by 0.01.
4. That gives 5 centimorgans.
5. Put another way, map distance in centimorgans equals the recombination frequency written as a percentage.
