A gene responsible for the elimination of paternal mitochondria in the offspring has revealed how and why mitochondria are only passed on through a mother's egg and not the father's sperm. Mitochondria present inside the cells of nearly all multicellular animals plants and fungi organelles plays an important role in generating the energy that cells need to survive. The findings showed that a gene CPS-6 serves as a paternal mitochondrial factor that is critical for its degradation. Further the enzyme that CPS-6 encodes first breaks down the interior membrane of the paternal mitochondria before moving to the space within the
