valina [46]

Answer:

B

slavikrds [6]

Answer:

A unicorn is a mythical creature that resembles a horse with a horn on its forehead. The unicorn could use its horn for self-defense. Some unicorns might also have wings so they could help the unicorn survive by escaping predators quickly. W could be for a winged unicorn (dominant) and w would be a unicorn without wings (recessive). L could be for a long unicorn horn, and l could be for a short horn. C would be a lighter fur color and c would be a darker fur color. That's all I could come up with for now :)
