Question

how are mitochondrial genes typically inherited? an individual randomly inherits their mitochondrial dna from either parent. an individual inherits their mitochondrial dna from their mother. an individual inherits one copy of mitochondrial dna from each parent. an individual inherits their mitochondrial dna from their father.

Answer 1

An individual inherits their mitochondrial DNA from their mother.

The little circular chromosome contained inside mitochondria is called mitochondrial DNA. These organelles are the heart of the cell and are present in all eukaryotic cells. The only way for mitochondria and their DNA to be transmitted from mother to child is through the egg cell.

Mitochondrial inheritance: The mitochondria in this particular type of inheritance have their own DNA. Only illnesses resulting from mutations in the mitochondrial DNA are solely passed down through mothers.

Because sperm contain few mitochondria and these break down after fertilization, an individual's mitochondrial DNA is solely acquired from the mother.
