Mitochondria, cytoplasmic organelles that contain DNA (mtDNA), cannot be newly synthesized, and therefore, these organelles must be transmitted from parents (Hoekstra, 2000). In an organism with sexual reproduction, nuclear DNA is received from both parents (biparental inheritance). In contrast, chloroplast and mitochondrial genomes are received in a non-Mendelian manner from one parent (uniparental inheritance) (Birky, 1995). In plants that produce flowers (angiosperms) and animals, the mitochondrial DNA is usually transmitted from the maternal parent (Hoekstra, 2000)....
