Uncommon Knowledge: Did you inherit DNA from both parents?

Yes and no. The kind of DNA that we typically think of in our cells, which is responsible for giving you your father’s nose or your mother’s dimples, definitely comes from both parents. However, that’s not the only kind of DNA you have. Inside your cells are a variety of “organelles” that perform specific functions. One of those, the mitochondrion, is known as the cell’s power plant. It also happens to contain its own independent set of DNA. Research suggests that this genetic material actually has a separate evolutionary origin than our regular DNA, and that mitochondria may have once been bacteria that established a symbiotic relationship within our cells. The other surprising fact about mitochondrial DNA? Children only inherit it from their mothers.

Thanks, Mom!
