In recent years,DNA sequences (nucleotide sequence) of maternal DNA and Y-chromosome were considered for the study of human evolution ,because :

A

they can be studied from the samples of fossil remains

B

they are small and, therefore, easy to study

C

they are uniparental in origin and do not take part in recombination

D

their structure is known in greater detail

Text Solution

Verified by Experts

The correct Answer is:
C
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 they are uniparental in origin and do not take part in recombination
