The coefficient of coincidence equals the number of double crossovers observed divided by the number of double crossovers expected on the basis of the single-crossover frequencies. The interference equals 1 - the coefficient of coincidence; it indicates the degree to which one crossover interferes with additional crossovers.
-In analyzing the results of a three-point testcross, a student determines that the interference is ?0.23. What does this negative interference value indicate?
A) Fewer double crossovers took place than expected on the basis of single-crossover frequencies.
B) More double crossovers took place than expected on the basis of single-crossover frequencies.
C) Fewer single crossovers took place than expected.
D) A crossover in one region interferes with additional crossovers in the same region
