Paternal inheritance

Definition
noun
A form of inheritance wherein the traits of the offspring are paternal in origin due to the expression of extranuclear genetic material (e.g. mitochondrial DNA) that entered the ovum during fertilization.
Supplement
It is a common notion that mitochondrial DNA is largely derived from the ovum. However, there were recent reports and cases of mitochondrial diseases that indicate inheritance of paternal mitochondrial DNA.
