Answer: tongue should be 50 and no tongue should be 50
Explanation: the dominant trait (T) will over power any (t) recessive when put together so Tt would result in a tongue due to the dominant trait being present. With two recessive (tt) that is when the trait will shine through. So (Tt) is on the box twice making if 50% and the (tt) is the other 50%. If you have anymore questions please don’t be afraid to ask:)
Hope this helps
