Homosexuality: A Genetic Analysis

Regarding the sexuality that defies Darwin’s theory of natural selection, what are the hidden genetic factors that influence homosexuality in humankind? Such a question has been delved into and investigated by two researchers who claim they may have what could be considered a revelation. They’re findings reveal that there may be two aspects of our biological creation in play, the first originating from studies conducted on families. The inquiries led them to a variety of families, but the most notorious of families were the ones consisting of multiple brothers and twins. They concluded there was an estimated 33% chance in identifying as a homosexual if said person had an abundance of older brothers. About the twins; it is assumed that having …show more content…
The table they created further proves what was set out to be tested, which is whether or not having a copious amount of homosexuals on the maternal side effects the participants’ sexuality. The findings indicate a resounding yes, granted; this is only a small portion of answering the overall mystery. Going back to the theory on whether siblings had an effect on each other’s sexuality; it was no shocker to learn that many of the homosexuals who participated in the survey did in fact have a lot of older brothers. Moving on, a different study led them to their second biological reason for homosexuality. For this portion of the investigation, the team of researchers focused on how sexual orientation is developed in the fetal stages of human development. They found evidence for them to be able to making a strong assumption about the “correlation with late birth order and an excess of older brothers” and homosexuality. The team that worked on these findings established the following theory: as mothers continue the path of frequently having male sons, eventually the brain somehow immunizes the natural differentiation of sexual orientation, resulting in greater chances of being a homosexual rather than a …show more content…
Instead of primarily focusing on the closest of kin of those who were surveyed, they extended it so both the maternal and the paternal line of relatives were involved. The objective was to determine the biological factors in sexual orientation (if any) that may be found when one broadens the research to the other family members that both homosexual and heterosexuals have. A fascinating result was found during the investigation, that being that the fecundity of female relatives (particularly mothers) of homosexuals was considerably higher than those of heterosexual
