Hagrid is interested in breeding Hippogrifts, a magical creaturewith the head and wings of an eagle and the body, rear legs andtail of a horse. Hippogrifts usually have steal color beak(b+), orange eyes (r+) and sharp talons(d+). In a cross between a true-breeding Hippogrift witha black color beak(b) and orange eyes (o+) and sharptalons male (d+) and a very rare-true breedingHippogrift with a steal (b+), ruby eyes (r) and dulltalons (d). He obtains only F1offspring with steal color beaks(b+), orange eyes (r+) and sharp talons (d+).However, if the F1 males were bred to the rare Hippogrift with ablack (b) beak, ruby eyes (r) and dull talons (d), he obtains thefollowing Hippogrifts. Hagrid was very confused with this data. Heasked Hermonine to explain the outcome to him.
