(B) Mutations in mitochondrial DNA in humans can lead to diseases such as Lebers hereditary optic neuropathy, which is inherited paternally.
(C) In plants, mutations in chloroplast DNA, which is typically inherited from the mother, can not lead to variegated leaf patterns due to defects in photosynthesis.
(D) In most cases, both maternal and paternal mitochondrial DNA contribute equally to the offspring's mitochondrial function in plants.
