Twin Studies

This essay discusses twin studies with placeicular accent mark on the role of genetic science on news program operation and ainity characteristics. There has been an ongoing debate whether intelligence and personality is based on genetic predisposition or not and basing from existing literature, twin studies commemorate significant evidence that genes do play a significant part. Separated Twins Twin studies realise been beneficial and informative regarding the mentioned debate. Identical twins become a good medium to learn from as they are 100% genetically the same. In a situation where the twins are separated and reared isolated, what happens?In a work written by Lawrence Wright, he relates the story of female identical twins that grew apart and was reunited. He said that since they are genetically the same, one could evaluate the environmental effects on the twins personalities, their behavior, their health, their intelligence (1997). In this particular study, the twins, Am y and Beth, were brought to two separate homes after birth. Amy was placed in a family where she was seen as a problem and was interact like an outsider. Amys mother was physically unfit and suffered from low self esteem.In contrast, Beth was treated well in the family she was adopted in and her mother did everything she can to make Beth a real part of the family. The results showed that during childhood, both child manifested same habits as thumb-sucking, nail-biting, blanket-clenching, and bed-wetting. (1997) Moreover, they were both afraid of being left alone. Both had indoctrinate problems and problems among friends and schoolmates. Though Amy had a good mother, her psychological tests show she had a longing for maternal affection, which as well-kept by Wright was eerily the same as her identical sisters (1997).Apparently, basing from the results of the study, despite growing up in assorted conditions, Amy and Beth were alike pathologically (Wright 1997). In addition to this , Wright mentions that Matters that instinctively seem to be a reflection of ones personal experience, such as political orientation or the degree of religious commitment, have been shown by various twin studies to be partly under genetic control (1997). This demonstrates how significant a part genetics play alongside environment.On the basis of this study, Wright believes that despite external factors, genetics still rule and determine a persons traits. Conclusion Despite the significance of twin studies, especially like in the issue of Amy and Beth, it appears that much of what a person becomes may be considerably attributed to genetic factors. However, as Wright himself says, this discipline has been debated on for centuries. On regards intelligence, it still cannot be established as there are variations among IQ results of both fraternal and identical twins.According to Medical News Today, there are indeed hereditary factors that affect the size of the brain. However, the mec hanisms by which interaction between genes and environment occur throughout life as well as kinetics of brain structure and its association with brain functioning still remain unknown (2007). This suggests that further studies regarding the matter is necessary to arrive at a conclusion. Twin studies will continue to be useful in further discoveries on the study of genetics and its relationship with human intelligence and personality development.
