Question

Quizplus · Accepted Answer

Leber's hereditary optic neuropathy is caused by a mutation in the mitochondrial genome, which is inherited maternally and not subject to normal Mendelian inheritance patterns. Therefore, it is not caused by genomic imprinting, X-linked or Y-linked inheritance, or a mutation in the plastid genome.
