Actually they dont have "Hermie" genetics, but rather your particular growing environment does NOT match what their ancestors are used to, so despite the environment being optimal to one strain of plant, this strain is stressed. this stress results in hermaphroditism to survive this frightning new environment and ensure offspring. Then the offspring that stresses more easily in your environment has genetic traits that lead to stress in its offspring when grown in your environment. Now two F1 siblings sisters. One hermies from stress in your environemtn, the other doesn't stress. Just like potency or flavor the likelyhood of each of these sisters offspring is different on their chances of reacting with stress (and increasing hermie tendancys) to your environment. Thus breeding with a hermie ensures similar environemnt will cause more hermies. In otherwords what may be damned hermie genetics that suck in your neighborhood might be awsome never hermie genetics to someone half way around the world in an entirely different lattitude.
