Draw a table that is 2x2. On the top, write a capital R over on box and a lowercase r over the second. On the side, write a lowercase r next to one box and another lowercase r by the other. The top left box would have Rr. The top right would have rr. The bottom left would have Rr and the bottom right would have rr. The probability would be 50%. There is a 50% chance of having wrinkled seeds
