The Plates Problem
Try breeding some offspring to see results of these crosses. Does the pattern of inheritance of plates tell you anything useful?
Based on your breeding experiments, where might you expect to find the gene for plates (i.e., On which chromosome might the gene be located?) Why do you think this is correct?
Dragons that grow plates usually do so quite late in their life, so dragons that have a new baby don't know right away whether or not it will grow plates. Which trait(s) exhibited by a baby might help a mother dragon determine whether her baby will grow up to have plates?
