Which sentence from the Newsela Article: Do you share more genes with your mother or your father? would be MOST important to include in a summary?

• Each cell in our bodies contains many copies of mtDNA because mitochondria replicate, or make copies

  of themselves, within the cell.

• Because all your mitochondria came from your mother only, you are more related to her than to your

  father.

• Mitochondrial DNA is different from nuclear DNA, or nDNA, which combines genes from both your

  mother and father.

• For decades, there has been one main theory explaining why mitochondria are inherited uniparentally.
