I was expecting something more along the lines of actual genetics, in which case two ugly parents make stunning children all the time. It is called hybrid vigor. The overwhelming amount of our produce is bred this way. They will inbreed corn like made so that it is 100% homozygous, but do it in five different pools. The resulting offspring of any two inbreds from two different pools is amazing. Inbred corn plants are about 4-5 feet tall and ugly as sin, but their offspring are 8 feet tall and near perfect.
