Black looking cattle can also come from darker versions of their wild-type coloration which is actually a variable color that includes black and red (eumelanin and phaeomelanin) coloration. For example, see PPR Black Splash on our Color: Wild-Type page. True black colored animals actually have a dominant black (eumelanin) genetic allele that causes all the colored parts of the animal to be black and not red. Careful inspection of the animals and their ancestry can determine true black genetics. Genetic testing can confirm it.
