With a population of just under 100, dragons are now considered to be an endangered species. In an effort to both boost the population size and broaden the gene pool, a limited captive breeding program will be set up. Dr. Tracey obtains permission to harvest eggs and sperm from 2 individuals. Unfortunately, a labeling error occurred in the lab and the parental phenotypes are lost. Using the F1 offspring produced from the egg and sperm, determine the possible parental phenotypes.
Double wings are codominant with no wings.
Determine the phenotypes and genotypes for the parents using the provided pedigrees. In the F2 generation, some of the dragons have died mysteriously in certain breedings. Explain how you can determine this and why or why not death occurs.
