Twin Studies

This essay discusses collimate studies with phonationicular emphasis on the role of communicables on intuition and personality characteristics. There has been an ongoing debate whether intelligence and personality is base on genetic predisposition or not and basing from existing literature, couple on studies show of import evidence that genes do play a signifi hatfult part. Separated Twins Twin studies have been beneficial and informative regarding the mentioned debate. very(a) match become a good medium to learn from as they are 100% genetically the corresponding. In a situation where the twins are separated and reared apart, what happens?In a work written by Lawrence Wright, he relates the story of female resembling twins that grew apart and was reunited. He said that since they are genetically the same, one could evaluate the environmental effectuate on the twins personalities, their behavior, their health, their intelligence (1997). In this particular demand, the tw ins, Amy and Beth, were brought to two separate homes afterwards birth. Amy was placed in a family where she was seen as a problem and was do by 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 schooling problems and problems among friends and schoolmates. Though Amy had a good mother, her psychological tests show she had a thirst for maternal mintion, which as maintained by Wright was eerily the same as her identical sisters (1997).Apparently, basing from the results of the study, despite growing up in different conditions, Amy and Beth were like pathologically (Wright 1997). In addition t o 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. consequence Despite the significance of twin studies, especially like in the field 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 matter has been debated on for centuries. On regards intelligence, it still cannot be realised 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 passim life as well as dynamics of brain grammatical construction and its association with brain functioning still remain unknown (2007). This suggests that only studies regarding the matter is necessary to arrive at a conclusion. Twin studies give continue to be useful in further discoveries on the study of genetics and its relationship with human intelligence and personality development.
