Assertion is correct,but Reason is incorrect.

(C) Pseudoalleles are genes that are located very close to each other on the same chromosome and are functionally related,often affecting the same trait or character.Since they are closely linked,they show very low recombination frequency.The Reason is incorrect because pseudoalleles do not affect different characters; rather,they affect the same character or trait,which is why they were historically confused with alleles.Therefore,the Assertion is correct,but the Reason is incorrect.
