Appearances for them, food may taste peculiar to them, odors may become repulsive, sounds may become either unbearable loud or scarcely audible.Regarding the root cause of this chronic mental disorder, researchers are still uncertain whether it is a biological disorder or a transitory emotional disorder brought about by environmental cause, as they explain their current understanding based on their study research that no specific gene has yet discovered, nor biochemical has been confirmed responsible, nor particular stressful event that sufficiently stimulate schizophrenia (Sumrall, 2003). But even no specific gene can cause this mental disease by itself, scientists have accepted the fact that the closer one’s blood relationship to a schizophrenic, most likely he or she will become afflicted because it runs in families. But additionally, scientists also believe that environmental factors, such as exposure to certain viruses or malnutrition before birth, or any other yet unknown psychosocial factors and problems during birth, are contributors to development of this illness (NIMH, 2009). Thus, undoubtedly, schizophrenia as an inherited mental disease is a well-established fact. In fact, as genes of parents are being transferred to their children, about 10% of probabilities to children of either a father or a mother is a schizophrenic tend to develop the disease, while approximately 50% to children whose parents are both schizophrenic 2001). It is now well-established that genes play a role in the development of schizophrenia. Genetic research, which involve studies on family, twin and adoption scheme while employing neurological and clinical observations, have been performed to provide basis of genetic transmission of cases of schizophrenia. One employed scheme is through comparing the concordance rates along with the monozygotic twins (MZ), who share 100% of their genetic substance, against dizygotic twins (DZ), who share only 50% of their genetic material. The results revealed an approximate concordance rate of 53% for MZ pairs while 15% for DZ pairs, hence, three times more likely MZ twins has genetically components of schizophrenia as compared to DZ twins. Moreover, children born to non-schizophrenic parents but were adopted and raised by schizophrenic parent did not show up probable rates of schizophrenia (Faraone, Taylor & Tsuang, 2002).Nevertheless, since no specific gene is found to be responsible
