When was the first mitochondrial DNA inheritance pattern identified?
Human BiologyGenetics
Quick Answer
Mitochondrial inheritance was recognized in the 1980s. It was shown that mitochondria are usually inherited from the mother.
The Full Story
The maternal inheritance of mitochondrial DNA became clearly established in the 1980s. Researchers showed that most mitochondria in a child come from the egg cell rather than the sperm. This finding was important because it explained a class of inherited diseases that do not follow standard Mendelian inheritance. It also became a powerful tool in evolutionary biology and ancestry studies.
