Mitochondrial DNA
In addition to the Y chromosome, there is a source of DNA that is inherited exclusively through the maternal line. This is mitochondrial DNA. The mitochondrion, like a bacterium, has its own circular DNA and its own ribosomes (similar to bacterial ones) designed for protein synthesis. During fertilization, the sperm does not bring mitochondria with it, so they are inherited only through the maternal line and are present in both men and women.
