Solution:
Mitochondrial DNA and Y–chromosome are useful for studying human evolution because they are uniparental in origin and do not take part in recombination. Mitochondrial DNA have several benefits over nuclear DNA as
1) mt-DNA is inherited from mother only hence, have single lineage.
2) No recombination in mitochondrial DNA.
3) High number of copy.
