| Abstract: | Three investigations in cattle nose and coat color, and body spotting inheritance did result in several hypotheses. In Gray Brahman cattle, black ear tipping appears to be inherited as a simple recessive. Wild-type nose color from the E⁺ gene appears to be modified by an inhibitor gene, I, found in Charolais cattle. In Angus cattle which do not possess the wild-type gene, black nose color is not affected by the inhibitor gene. Observations at Mc Gregor suggest that the blaze gene is not present in the Charolais breed. |
