The correct answer is D: The Y chromosome changes much less than other chromosomes.
Explanation: Researchers look at the Y chromosome for ancestry studies because it is passed down relatively unchanged from father to son. This stability allows scientists to trace lineage and understand ancestral relationships over long periods. In contrast, other chromosomes may undergo more significant changes due to recombination, making the Y chromosome a more reliable source for studying male ancestry.
