The Sound of Science - "Genes from our Parents"

Nov 2, 2018

Kate: Welcome to the Sound of Science on WNIJ. I’m Kate Powers from NIU STEM Outreach. Today we have a question from Marcella. She wants to know what percentage of our genes come from our parents. Marcella, it depends on who bought the denim pants and how many pairs you already have.

Sam: That’s not what she had in mind. She wants to know about DNA, not dungarees. Obviously we get 50 percent of our genes from our biological mothers and 50 percent from our biological fathers.

Kate: And 8 percent from viruses.

Sam: Viruses?
