[QUOTE="Jeanne - Simme Valley, post: 1725488, member: 968"] I don't know the scientific explanation, but I do know a "trait" can skip generations and pop up further down the line. Like for me, I hate heavy front ends. There might be a son or daughter out of a short, thick fronted cow or bull that has a beautiful front, just what I love. I generally will not breed to that offspring because I know, sooner or later, the ugly front end will come back and bite me. I'm an old timer, I don't have the lingo to explain, I just know. LOL KISS - use the horn trait gene. You might go 5 generations with no horned calf, but OOPS, there's a horned calf. All it takes is just 1 of the horn gene to keep getting passed down without ever getting the 2nd horned gene from the other parent to be expressed. Then 5 generations later, that animal is matched up with another animal that is carrying the hidden horned gene and BOTH parents happen to pass their horn gene down to the offspring. Now you have a horned calf. This is an easy explanation of a one recessive gene. Takes 2 to be expressed. A dominant gene is much easier to follow. If it gets passed by one parent, it is expressed. So cattle can carry good or bad genes that are not expressed until mated to another animal with the same hidden gene - if they are recessive. [/QUOTE]
