[QUOTE="Anonymous, post: 14606"] To add to Dun's comments. First, what I say does not hold true for "eared" cattle. Their horn/scur genes are different. If an animal is horned/scurred, you will never see any sign of scurs. The horns are dominate. Scurs are a sex-linked gene. In males, the scur is a dominant gene. In females, it is recessive. Meaning, a bull only has to inherit 1 scur gene to express (show) the scurs. The heifer has to inherit a scur gene from both the dam & the sire. So a female can be polled/scurred and you would never know it if she only inherited 1 scur gene. She would have a clean polled head. If either the bull or heifer calf is horned, you will never know if they are carrying the scur gene. At a young age, it is VERY difficult to tell if it is a scur or horn.
