In peas, the allele for tall (T) is dominant over short (t), and the
unlinked gene for seed coat has the allele for smooth coat (R)
dominant over wrinkled coat (r). The expected phenotypic ratio of
offspring from the cross Ttrr x ttRr would be:
9 tall, wrinkled: 3 tall, smooth: 3 short, wrinkled: 1 short, smooth
3 tall, smooth: 3 tall, wrinkled: 1 short, smooth: 1 short, wrinkled
O
1 tall, smooth: 1 tall, wrinkled: 1 short, wrinkled: 1 short, smooth
O 3 tall, smooth: 1 short, wrinkled
9 tall, smooth: 3 tall, wrinkled: 3 short, smooth: 1 short, wrinkled
