Sexual Orientation

Twins - Not so identical after all

Whenever we see identical twin babies, we usually stop and say "how cute...", especially if they are dressed alike - then they are just outright adorable! Sometimes it is even difficult to tell whom is whom when they have the same facial expressions,  or if they do everything the same and speak alike that they appear to be just one sole person. We wouldn't for example be able to tell between Jack and Mack, unless they told us themselves.  Although, it turns out that some twins are not so identical in everything. What if Mack turns out to be a homosexual, and Jack a heterosexual. Then we would be able to tell whom is whom.  It turns out that monozygotic twins are more likely to have different sexual preferences compared to dizygotic twins. Meaning that one twin might be a heterosexual, while the other might become a homosexual. However that is not to say this is true for all twins, they can both be heterosexual or homosexual for that matter. In the following video, it explains how homosexuality in a twin can be derived during their development in the womb. A hypothesis in the video explains how some scientists believe that a twin can become a homosexual due to not receiving enough testosterone in the brain. That they do receive adequate testosterone to develop physically as a male, but there is not enough testosterone to orient them in being attracted to females. This video segment follows twin males and thus they're explanations are mostly related to males. 

However, I believe that a person has a choice in being either a heterosexual, homosexual or both if they want. I agree that it is interesting to investigate if there is a biological explanation to choosing a sexual orientation, but I just hope that it doesn't lead to people wanting to prevent that from happening or trying to find a "cure" for people who are under this "condition". Which is why this is a controversial topic in which many people will either disagree or agree with one another.
