Assertion: Aneuploidy may be of hypoploidy or hyperdiploid type.
Reason: Monosomy lacks one pair of chromosomes.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
(c) If Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(c) If Assertion is correct but Reason is incorrect.
Explanation:
Aneuploidy can be either due to loss of one or more chromosomes (hypoploidy) or due to addition of one or more chromosomes to complete chromosome complement (hyperploidy). Hypopliody is mainly due to loss of a single chromosomes, monosomes (2n - 1) or due to loss of one pair of chromosomes, nullisomes (2n – 2).
