A Study of the Relation Between Genetics and Same Sex Orientation

For a long time, people have been wondering about the idea of same-sex sex. This has been a controversial topic that needs a lot of research to be proved right. Despite the efforts of the scientists to get to the basis of the matter, many discouragements have been put into place with several world religions and beliefs sticking to their doctrines and what they believe in.

nonetheless, several studies have been carried and despite the errors that have been noticed, the results are confusing and at the same time fascinating.

Studying the behavior of humans and their characters is not easy. Establishing a biological base that underlies the same character is one of the most important things that scientists can do. This essay will focus on scientific proof that indicates that someSexxx urges can be associated with genetics despite the numerous challenge and threats from those who believe and try to [prove that is not.

The media has been at the forefront of informing the people on developments that are associated with same-sex issues.

However, they have continued to confuse the people every day since aZhengll sorts of information have been given with most of them contradicting and this does not make the information they present satisfying. Those that have the urge for the people of their sex are running to prove that their state is genetic and that they should be allowed to marry each other while those that are not are working to prove them wrong and this has brought about a lot of mayhem which makes it important for scientists to shed some light into the genetic status of these people.

At the beginning of the year 1990, several activists began arguing that homosexuality has been proven to be genetic Zheng, Zheng, and Martin, p16289). At this time, few studies had been carried out to provide substantial information regarding this issue. At this time-sex sex, enigma was associated with several things ranging from the differences in the inner ear, differences existing in parts of the brain, the length of the fingers, eye blinking, genes, and variations in neuro hormones.

Research that was carried out by a Columbian university doctor indicates that research done on more than 200 people yielded fascinating results. In the research, the subjects of the study confessed that reparative therapy counseling helped in the reduction of the same-sex partner desire, and some claim that they were able to change to heterosexual (Stewart and Craig, p147). While another research proves that bisexuality is a fashion among many young people who move from being normal to bisexual to gay to homosexual to normal. Other recent developments have indicated that lesbians in women can be associated with emotional attraction and this changes over time. A study carried out in 1994 on women attracted to their gender indicates that two-thirds of these women were able to change from their current condition Nonetheless, a study carried out on genes and mice brains indicates that sexual identity is genetic. This is because the hormone that is associated with this whole process is based on genetics. The milieu hormone existing that makes the differences in homosexuality between men and women is determined by the genetic status of the people. If this is the case in these animals, then the same case applies to humans since they are not much different. As such, we are all animals, and we have our own sexual identity which is determined by something. Some hormones in this case help in the determination of the sex status of each one of us. Now that people have choices to make, it is very hard to go against what the body desires thus, the gays and the lesbians move towards their hormonal sex orientation (Balthazart and Jacques p1). This is a confirmation that sexuality is genetics determined.

Additionally, research done on the hypothalamus indicates that there are differences in the structure of the brain in homosexual and heterosexual men (LeVay and Simon p253). It indicated that the heterosexual men have larger hypothalamus than the homosexual which indicates that there is a biological orientation of sexuality. Even though his subjects died of HIV AIDs which might have caused the differences in the brain structure, this was significant proof of undeproofmal circumstance that sexuality has biological bases. 

Also, research done by several researchers in NCI linked homosexuality with the x chromosomes. It shows that there are DNA markers indicating identical sequences in the x chromosomes of 33 gay brothers which indicated that sexuality has genetic bases (Hamer, p321). The research shows a similarity in these brothers which might be proof that people with what is termed a sexual disorder have something in common. The genetic characteristics of these people were evident which shows that sexual orientation is genetic.

In the year 1991, a study carried out on fraternal and identical twins indicated that more than half of the identical twtwin’subjects that were studied displayed were homosexual while only 22 percent of the fraternal fell into the same category. This indicates that sexual orientation has a genetic basis since the identical twins share the same genetic material and had a higher percentage of the number which indicates that genes had largely contributed to these results.

Besides, in 1998 a study was conducted on hormones by Pasanen and Dennis McFadden which evaluated the hearing system (McFadden, p341). The study well thought out the alterations in repeat-like waveforms released from an internal structure of individuals who have no problem with hearing. Scientific study suggests that these waves armored e advanced in women than in men whereby this is a factor that led to the number of pebecomingecome men in their early formation as a fetus. In the study, it was discovered that the waveforms varied between those of women who are sexually attracted to men and those of men regarding the self-acknowledged lesbians. based on this study, the researchers concluded that a vast exposure to the formation of a male fetus in the womb would result from female homosexuality contrary to the homosexual men Also, they said that manipulations from certain drugs, sounds that are displaying a distinctive feature to a heightened degree and so on can cause la ow level of these waveforms.

Thus, this concluded that it may be something in the manner of living that reflects the bisexual females and homhomosexuallues and attitudes which lead them to be disclosed to one or mo e representatives who has a waveform that is low for a limited time only or for a long time without essential change.

Additionally, another study was conducted by Dr. Breedlove in 2000 regarding the size of the finger which results indicated that lesbians had more extended fingers than other women. This was affected by the massive exposure in the womb to the male hormone (androgen) (Breedlove and Marc p341). Typically, the ring finger is always taller than the index finger considering for both males and females through in women they are almost the same size in men the ring finger is more observably longer. Breedlove found out in the study that the size of women’s fingers had started following the men’s form.

Also, in October 2003, authors found out that in the study of eye blinking, the prepulse inhibition of human startle was more in women than in men and thus, lesbians’ response was much slower than other women. Regarding the study, the authors came to a suggestion that homosexuality is a preborn condition reason being that startle retort is not learned but involuntary (Kinney and Morgan). This high power proved that orientation is characterized by high determination before birth.

In conclusion, determining whether homosexuality has a genetic link is difficult. Many studies that purport to prove that homosexuality is inborn are correlational and inconclusive. In the case like that of the twin studies, there is strong evidence that shows that the early childhood environment is the paramount factor that determines the development of homosexual desires. Dr. Satinover argues that there are some interesting statistical relations between two factors that people misuse to advance political agenda. An example is looking at the basketball players. They are tall meaning that their height correlates with the game they play but this does not mean there is a gene for basketball. He further puts it that some individuals may be made susceptible because of prenatal hormonal influences, hereditary or other brain or physical deviations to possess the complex of all attributes that make them susceptible to attack to the environmental factors that can call forth homosexual wants thus homosexual is not biological as the activists and the media try to demonstrate it.
