Psychology

Twins can either be fraternal and identical. Whereas monozygotic twins have identical genetic sequence since they were fertilized from a single egg fraternal or dizygotic twins share fifty percent of genetic material but ate utterly different to the extent of finding a male and female. Thus studies have been postulated to discern how the similar genetic make up in monozygotic twins affect their relative life within a given environment so as to perceive if some character traits, diseases and behavioral changes can be wholly be attributed to genetic formulae. Accordingly studies have theorized that there is a high correlation of shared intelligence and IQ semblance between identical twins as opposed to fraternal twins. Consequently, research findings have disclosed that identical twins can engage in similar activities though sometimes far apart.

According to Arnold Gesell, Ph.D., a pioneer in the twins psychology study, he unveils that identical twins behavioral activity is determined by a genetically preconceived and predetermined channel of activity that sets them rarely apart from the daily activities. Thus Arnold Gesell conducted an experiment in which one twin was trained on how to climb stairs and after some time the untrained twin seemingly learnt the skills with relative easy(Gesell, 2009). Nevertheless, other professors have disputed the idea citing that such a scenario is of little implication as to denote the behavioral change since children can learn climbing of stairs by observation. Therefore familiar family environment can not be separated from the said similar attributers that are accorded to the research since according to Jay Joseph, family environment is a characteristic and trait significant (Jay, 2004, 86). Reflectively it has been observed that identical twins share the same environment more specifically than fraternal counterparts thus making them quite relevant for behavioral studies such as sexuality, crime, lifestyle and intelligence. Identical twins have thus been found to have similar reactions to different stimuli which qualifies that indeed some behaviors are hereditary and to a large extent they interpret the environmental stimuli concordantly. Parental care has been attributed as a major factor that also contribute to the way twins perceive the world though their significance diminish with the inclusion of other siblings in the family. Conspicuously, the way parents treaty their children almost follow a systematic pattern as from the first borne to the rest and yet the same treatment can never be the same in regard to diverse individuality that can be displayed in a single family. Therefore, identical twins reaction to the environment stimuli is dependant on their peculiar ways to perceive the same stimuli and the meaning they decide to attach to a given situation is varied according to their internal manipulation of information received (Jay, 2004).

Equal environment that identical twins are exposed to affects their collective moral activity and consequently have a notable effect on their eventual character and way of life. In studies that have so far been conducted to the effect of establishing whether homosexuality is genetically predetermined. Tim Taylor claims that homosexuality behavior can be proven to be either genetically predetermined if there is 100 concordance being observed in the identical twins while some degree of varied traits is allowable in the character of fraternal twins. Some results correspond to the genetically oriented homosexuality behavior whereas majority of unbiased studies in the selection of twins for sampling have declared lack of correlation the results obtained to conclusively point to homosexuality being hereditary (Tim, 1997). Reflectively, it us possible that twins borne to environments that practice homosexuality tend to pick such behaviors leading to the subjective claim that identical twins confess to homosexuality then conclusively homosexuality is genetically predetermined (Whitehead, 2008). However, following indications that identical twins reared apart seem to be able to recollect the diverse experiences and relate with each other as if they were reared together then maybe a claim can be said that if one is drawn into homosexual acts, then proportionally the other twin is as well drawn to the sane stimuli by identifying with it on personal-environmental based level far from genetics.

Twins separated at birth to indicate that environmental factors and presence of diversely applied different stimuli are being exposed to the twins at different time frames Still and in particular to identical twins  there seem to be a correlation in the in observed behavior. Though this can point out to their ability to perceive emotions similarly hence wherever there is a case of coincidences it should not be confused with the fact that they seem to have a similar communication system within their minds thus they may perceive a stimuli and interpreted it similarly(Tim, 1997). Therefore if these identical twin by virtue of them perceiving a given stimulus correspondingly is no reason enough to engage genetics rather, that the psychological and physiological environment that they perceive affects how they react. Therefore it is possible to be able to trace some twins who are practicing a given trait while the other is overwhelmingly dissimilar. Dr. Beetle, author of Identical Twin Studies and Evolutionary Psychology asserts that though the DNA of identical twins is 100 matched their similar behaviors arise from the surrounding structures and a desire for mimicking in order to create bonding as soul mates. As such, the author insists that similar environment perception and body system reflects that they understand their body language with relative easy.
In conclusion psychological genetics research and study that concerns the idea that some character traits are genetically influenced may be misguided since broad research is pointing out to mimicry and behavioral influence stimuli. Therefore behavior of twins cannot be separated from conduct of individuals in a closed group who may even tend to look alike. Family life also cements twins together and more so the idea of identicalness contributes to peculiar traits that a twin may exhibit. Reasonably, a son who takes after a father will tend to mimic the fathers activities and so is the psychology behind twins and their similar behavior.
