Approximately 40 percent of cats with white fur and blue eyes are completely deaf. In cats with one blue eye and one eye of a different color, deafness occurs only on the blue-eyed side. White fur, blue eyes, and deafness are linked to a single pleiotropic gene in cats. Based on the information above, it can be concluded that pleiotropy occurs when A. one trait is influenced by many genes. B. a trait is influenced by both genes and environment. C. one gene influences multiple traits. D. a trait is not influenced by genes.
