Overview
Cytoplasmic inheritance, particularly through mitochondrial DNA, is a fascinating aspect of genetics that highlights how traits can be passed down from mother to offspring. Unlike nuclear DNA, which is inherited from both parents, mitochondrial DNA is exclusively maternal, making it a unique tool fo...
