Vedclass · Answer

(B) Chromosome maps are based on the frequency of recombination between genes. However,they are not perfectly accurate because of the phenomenon of interference. Interference occurs when one crossover event in a specific region of a chromosome reduces the probability of another crossover occurring in the adjacent region. Furthermore,multiple crossovers can occur between two genes,which may not be detected as recombination,leading to an underestimation of the actual physical distance between genes on the chromosome.
