I'm really confused on my notes.. Can someone help? An excited grandma and grandpa await the birth of their first grandchild. They are so excited to know what they will look like the decide they should make a Punnett square and predict. The grandma has a widows peak (A) and her husband has a straight hairline (B). Both the other sets of grandparents have a straight hairline (C & D). Note: widow's peak is dominant. (There's an E on the top left, F on the top right, G on the bottom left, and H on the bottom right. These things have always confused me and my teacher hasn't given coherent help..Can someone explain this?)
