Vedclass · Answer

(D) The distance between genes is directly proportional to the frequency of recombination (crossovers). Since genes $A$ and $B$ are closer than $A$ and $C$,the recombination frequency between $A$ and $C$ is higher than between $A$ and $B$. This implies that $B$ must be located between $A$ and $C$ (sequence: $A-B-C$). Statement $I$ is correct because $A$ is at one end. Statement $II$ is correct because $B$ is between $A$ and $C$. Statement $III$ is incorrect because $C$ is at the other end. Statement $IV$ is correct because a greater distance between $A$ and $C$ results in more crossovers. Therefore,statements $I, II$,and $IV$ are correct.
