Sequences in MtDNA and the Y Chromosome Provide an Interesting

Sequences in mtDNA and the Y chromosome provide an interesting perspective on the early migratory routes of H. sapiens. Both mtDNA and Y chromosome data are useful because these molecules do not undergo recombination. Which of the following statements also provides support for their utility in estimating origins of various groups within H. sapiens?

A) Mutation rates are lower in mtDNA and the Y chromosome so rates of evolution are slower than rates across the genome of H. sapiens.
B) mtDNA and the Y chromosome can give information about interbreeding between different species of the genus Homo.
C) mtDNA provides less information on origins of H. sapiens than Y chromosome data because it is only inherited through mothers.
D) mtDNA and Y chromosome data don't hold as much data as the genome because they are so small and have a small relative number of base pairs.
