the mother and father.
either parent.
the mother only.
mitochondria are not found in mammals.

Explanation:

In most mammals, mitochondrial DNA (mtDNA) is maternally inherited. This is because the mitochondria from sperm cells are typically destroyed during fertilization, leaving only the mitochondria from the egg (maternal source) in the developing embryo. Mammals do possess mitochondria, which are essential organelles for energy production.
