This is a very very off topic question but I was curious if anybody saw the show on national geographic called Genetics. It was basically about how science can alter genetics in their favor. Anyway I thought it was crazy how they could remove something in the dna of a normal cow and it would turn into a super-cow as i like to call them. By changing the genetics the fully grown cows were able to pack on an extra thousand pounds of lean muscle. Its crazy just curious if anyone knows anything further about this.
