1) 75% purple flowered and 25% white flowered. If you complete the punnett square, you'll see the combinations are PP, Pp, Pp, and pp. The capital P is dominant (purple), so you know that 3/4 combinations will be purple flowers.
2) 50%. There is a 50% chance Grace will have Huntington's disease because since the disease is dominant, it is capital letter H. When you make a punnett square, you'll see the combinations are Hh, Hh, hh, and hh. There is a 50% chance Grace will have the Hh combination.
