Vedclass · Answer

(D) The $mtDNA$ (mitochondrial $DNA$) is inherited maternally,and the $Y$-chromosome is inherited paternally. Because they are inherited from a single parent,they do not undergo the process of genetic recombination (crossing over) during meiosis. This allows scientists to trace lineages back through generations without the 'shuffling' of genetic material that occurs with autosomal chromosomes,making them ideal markers for studying human evolutionary history and migration patterns.

Currently,the $DNA$ sequence of $mtDNA$ and the $Y$-chromosome are considered for the study of human evolution because:
