Vedclass · Answer

(B) Linkage refers to the physical association of genes on a chromosome. $1.$ Tightly linked genes are located very close to each other on the same chromosome,which makes the probability of crossing over between them very low,resulting in very low recombination frequency. $2.$ Weakly linked genes are located further apart,allowing for a higher frequency of crossing over and thus higher recombination. $3.$ Therefore,tightly linked genes show very low recombination,while genes far apart show high recombination. Thus,the correct statement is that tightly linked genes on the same chromosome show very low recombination.
