Iâve seen a few claims that red color has advantages over black. Supposedly more heat tolerance â makes some sense â wearing black clothes in sun obviously makes you hotter. Supposedly fewer flies â maybe black attracts more? Anybody else heard these arguments? And supposedly any color beats white. Herefords get more cancer eye because of lack of pigment. Udders get sunburned if no pigment. I know my wife likes flowers and such with color. She has complained that we have too many black animals â dog, cat, cows. Iâm thinking if I can get more colorful cows, sheâd let me spend more money on them. Only problem is, black gene is dominant over red. I have a black cow (angus/jersey) and black whiteface heifer (angus/jersey/hereford). So they each have a black gene and red gene. So if I breed to a red angus (two red genes), half their calves should be red. Am I figuring this right?
