If I remember correctly, you make a grid with 4 squares. One parent’s traits are written along the top (R, R), the other parent’s down the side (r, r). As you put them together in the boxes to show possible offspring traits, you find that each child will get one R and one r (Rr). So the answer is Rr only.
On the second problem, both parents are Dd, so you end up with 4 possibilities: DD, Dd, Dd, dd. Three of these have the dominant gene, so the answer is 3/4, which is 75%.
Best wishes to you!
