Given below are two statements:
Assertion (A): Linkage and Independent Assortment are opposing phenomena.
Reason (R): Independent Assortment occurs when genes are located on different chromosomes (or far apart on the same one), whereas Linkage occurs when genes are located very close together on the same chromosome.
Choose the correct answer:
