The Inheritance of Mitochondrial DNA ^^inzzr^

Mitochondrion Nuclear DNA MOST OF AN INDIVIDUAL'S GENES are located on DNA molecules in the cell nucleus. Mitochondria, the specialized structures that provide cells with energy, also carry some genes for their own manufacture on a ring of DNA. When a sperm and an egg cell unite, they contribute equally to the DNA in the nucleus of the resulting SPerm cell. All the mitochondria and the DNA they contain, however, derive from the egg. Studies of mitochondrial DNA can reveal an individual's maternal ancestry.
