2. re hornless cows
Mon Dec 3, 2018, 02:51 AM

Just to point out, Hornless breeds of cows already exist.When you see pictures of cattle such as in the west without horns they weren't dehorned, they never had them to begin with. Most all mainstream cattle breeds today are naturally hornless, "polled" is the term used such as "polled angus" "polled Herefords" ect. These polled cattle have been prevalent for a couple hundred years or so. What happens is like any genetic trait it takes 2 pairs of genes to create something such as horns hair color ect early breeders didn't know about genes like we do now but they knew every now and then an animal would be born that never developed horns so they used these animals to establish more offspring that were hornless. To clarify, this scientist isn't trying to produce cows in general without horns but is trying to make it happen in breeds which up until now obviously had no polled lines within them but the science itself has ben around for hundreds of years.
