DNA and genetic science can also be used to do this. breed dogs that would have long tongues breed cows that would produce more milk without using hormones breed horses that don't fall over when they fall asleep

## Step 1<br />The problem is about the application of genetic engineering in breeding animals. Genetic engineering is a branch of biotechnology that involves the manipulation of an organism's genes using biotechnology.<br /><br />## Step 2<br />The first part of the problem asks about breeding dogs with long tongues. This can be achieved by identifying the gene responsible for tongue length in dogs and then selectively breeding dogs that carry this gene.<br /><br />## Step 3<br />The second part of the problem asks about breeding cows that produce more milk without using hormones. This can be achieved by identifying the gene responsible for milk production in cows and then selectively breeding cows that carry this gene.<br /><br />## Step 4<br />The third part of the problem asks about breeding horses that don't fall over when they fall asleep. This can be achieved by identifying the gene responsible for the horse's ability to maintain balance and then selectively breeding horses that carry this gene.
