Davion is in the clinic for a check up. At birth, you diagnosed him with Treacher-Collins Syndrome, a genetic disorder that affects the development of the bones and other tissues in the face. TCS is believed to be caused by a change in the gene on Chromosome 5, which affects facial development. About 40% of the time, one parent has Treacher Collins Syndrome. If the parents of the affected child are not affected by the syndrome, the chances of a sibling having Treacher Collins are minimal. Which organelle in the cell is responsible for Davion's inheritance of this genetic disease?
