Vedclass · Answer

(B) The distance between two genes in a chromosome is measured in map units or centimorgans $(cM)$.One map unit corresponds to $1\%$ of crossing over (recombination frequency) between the two genes.Therefore,the cross-over units represent the percentage of crossing over between the genes.This is because the frequency of crossing over is directly proportional to the physical distance between the genes on the chromosome.

The distance between two genes in a chromosome is measured in cross-over units,which represent:
