The noncoding regions of mammalian mitochondrial genomes have little to no selective pressure. Which of the following are consequences of this condition?

A) a rate of mtDNA repair is much lower than that of nuclear sequences
B) noncoding mitochondrial DNA increases in nucleotide diversity more quickly than coding DNA
C) a rate of mutation that can increase with successive generations in a maternal line
D) a high rate of natural selection for genomes identical to those of the mother
E) a high rate of loss of mitochondrial genomes relative to nuclear sequences
