This appears to pretty much put an end to the thought that homosexuals are born that way, a blow to the anti-faith pop who've thought thus. 


"eight major studies of identical twins in Australia, the United States and Scandinavia during the last two decades all have arrived at the same conclusion: homosexuality primarily and overwhelmingly (90%) is an acquired disposition, instead of genetic."


"As a result of having the same genes and prenatal conditions, identical twins are perfect subjects for scientific study to determine whether a disease, disposition or personality attribute is caused by nature (genes) or nurture (acquired). If homosexuality is caused by genetics and/or prenatal conditions in the womb, then identical twins will always be identical for same sex attraction. That is, if one identical twin is homosexual, the co-twin should also be homosexual. In other words, the same sex attraction (SSA) concordance should be 100%."
