Mitochondrial DNA （mtDNA） is maternally inherited through several mechanisms that have been proposed （Luo et al., 2013） and, if mitochondrial mutations are inherited to the offspring, it is possible to cause mitochondrial diseases such as neuropathy, cardiomyopathy, myopathy, and liver failure.展开更多
