In promising news for dairy farmers, researchers have bred what are likely the first offspring from a genome-edited bull. The calves were born without horns, a trait that occurs naturally in cattle but that was given to their father through previous DNA-editing research. 



The offspring were otherwise normal and healthy, the authors reported Monday in Nature Biote
