The red arrows in Figure 1 indicate a normal open epiphyseal plate (an open growth plate).   What tissue is it made of? What tissue will it be made of once it has closed (fused)? Which bone is the growth plate part of? Describe how this growth plate formed. Start with the cartilage model in the embryo and end with what can be seen in this xray.

CRCR (red flowers); CRCW (pink flowers); CWCW (white flowers); F (full leaves) > f (slender leaves); H (heat tolerant) > h (vulnerable to heat) G*G? (green leaves); GʻG? (green and yellow leaves); G?G² (yellow leaves) CRCR Ff Hh G1G1 x CRCW Ff hh GʻG? Box 1: Which trait displays incomplete dominance? Box 2: What is the PHENOTYPE of the second parent in the cross? Box 3: What is the probability of having an offspring which is completely HETEROZYGOUS? Show your work by listing the fractions and how you would determine the answer (add, subtract, divide, multiply, etc).
