Q. In recent years, DNA sequences (nucleotide sequences) of mtDNA and Y-chromosomes were considered for the study of human evolution, because
A) Their structure is known in greater detail
B) They can be studied from the samples of fossil remains
C) They are small and therefore, easy to study
D) They are uniparental in origin and do not take part in recombination
Explanation
Wilson and Sarich choose mitochondrial DNA (mtDNA) for the study of maternal line inheritance, while Y-chromosomes were considered for the study of human evolution particularly male domain. It is possible because thay are uniparental in origin and do not take part in recombination.
