What genes are inherited from mother only?

And, mitochondrial DNA (or mDNA) is inherited strictly from the mom. Because mDNA can only be inherited from the mother, meaning any traits contained within this DNA come exclusively from mom—in fact, the father’s mDNA essentially self-destructs when it meets and fuses with the mother’s cells.
