Why Do We Inherit Mitochondrial DNA Only From Our Mothers?
We contain about 37 coding DNA within the mitochondria which has been proven we only inherit them from our mother. Study's has also shown that when inheriting the mitochondrial DNA from our father there is an occurrence of a mutation or may lead to embryonic death. There are some theories on why this may occur, for example researchers explained that when sperm is competing for the egg cell they tend to use a lot of energy and over work themselves, eliminate the DNA from the sperm and leading to the mutation.

It would be an interesting study to find out if any embryos have survived with mitochondrial DNA from the father. Although it isn't common, there probably is a few cases that may prove this.
