Homosexuality-theories compared and contrasted Research Paper

Homosexuality-theories compared and contrasted - Research Paper Example Two theories have been advanced to explain the origin of homosexuality; both are scientific theories though the social scientists have also contributed to the explanation by stating that it results from a social and environmental factor. In my view homosexuality is a human act that results from peer influence and the need to adventure and acquire knowledge of what is perceived to be against the norm (Lester,pp 123). 1.0 The Genetic theory This theory states that homosexuality as a human behavior is a culmination of the genetical constitution of a human body. It argues that’s there are genes that are responsible for the occurrence of homosexuality, these genes it states are homozygous in a recessive situation, and in the case of heterozygous case it will only be manifested if there is a diploid cell formation from another heterozygous situation (Bret,pp 243). This explains the reason as to why it is said to be hereditary and can be traced in a lineage. The genes are said to occupy the same locus in the genomic sequence (William,pp 229). This theory has been ignored for the obvious reasons that its assumes that only one gene is responsible for determination of sex in human beings, which is an obvious understatement 2.0 Theory of Neurohormonal His theory tend to explain the influence of hormones in homosexuality though different reports gives conflicting statements rendering the theory less efficacy on its explanations, its states that the prenatal hormones in association with the nervous system under a conducive environment during the gestation periods at the second to fifth month may results into a homosexual person, the theory proposes that when the nervous system comes into contact with hormones such as testosterone,estradial and some other sex hormones during neuro organization, then homosexuality results. The theory gives more weight to testosterone hormones as being critical during gestation period as being responsible for the development of homosexuality, this theory on the same principle explains the situation of monozygotic and that of dizygotic twins (Bruce,pp 198). Comparison of the two theories Its worth noting that the two theories have concurrence at some point, they all apprecia te that homosexuality is controlled by innate factors, the genetic one being that its controlled by the genes while that of the neurohormonal one is influenced by the hormones, in this way the theories tend to believe that the external environment actually do not plays any role in influencing the sexual orientation of an individual (Lester,pp 23). The theories also confirms that the status of homosexualism is hereditary and that it can be passaged from one generation to the next provided that the genitical materials of the homosexuals are constant, also for the neurohormonal theory, the presence of the hormones will dictate the occurrences of homosexuality, In addition to those both the theories also acknowledge the role of the environment in homosexuality, in this sense both accepts that for a homosexual individual to occur a enabling environment is necessary Which is correct? The question of which of the theories that explains homosexuality can be banked on has led to a ragging de bate as all have shortcomings: certainly all are not mutually
