Hi! My name is Sayantan ( @queersprings), and I am the current coordinator of @labhopping. I am #queer_trans and participating in the #GlobalScienceShow ( @globalscishow) on the occasion of #LGBTQSTEMday. I would be tweeting about the history of genetic research on sexuality.
Remember to follow the whole show, and check out @JuliaVSeidel, who is up next.
Do not forget to follow this #thread, @queersprings and @labhopping. Before we begin, let's do a quick poll. Do you think #sexual_orientation is #genetically_determined?

I will talk about #three #classical #discoveries, and we will try to evaluate these in the context of #ethics and #scientific_robustness. We will finish with an understanding of where we stand #now (i.e., in 2020).
1991: Bailey & Pillard compared the prevalence of homosexuality b/w monozygotic twins, dizygotic twins and non-twin siblings. Their data claimed that 52% of monozygotic twins show concordance for homosexuality, as compared with 22% and 11% respectively for the other categories.
In simpler terms, they claimed that there is a correlation between the amount of shared genetic material and the probability of two siblings being homosexual. Can you think of what might be the #drawbacks of the study?
Interestingly, this study did not find any correlation between childhood gender non-conformance and adult sexuality. :D
