Vedclass · Answer

(A) The frequency of crossing over is directly proportional to the physical distance between the two genes on a chromosome. As the distance between genes increases,the probability of a crossover event occurring between them also increases. Therefore,the frequency of crossing over serves as an index for mapping the relative distance between genes on a chromosome. Since the strength of linkage is inversely proportional to the distance between genes,crossing over frequency also indirectly indicates the strength of linkage,but it is primarily used as an index for relative distance.
