[QUOTE="ANAZAZI, post: 561317, member: 7541"] Yes but no! A cross between them will express the same muscle as their parents, as the animal will be heterozygous on both loci. However, if you in later generations can create an animal homozygous to both, or to all six mutations, then you have created a "super terminal" which sires double muscling no matter what jersey it is bred to! But this breed would be very similar in phenotype to the muscle breeds of today, as a branch will not be more broken if you break it six times.(the mutations can, if homozygous on their own stop the Hormone myostatine from working, a hormone that regulates muscle growth) [/QUOTE]
