very brief and simply to say : 1)like that fetus for a couple of weeks is sexless, and after a period of time, depending on the chromosomes it has XX, XY,.. male or female hormones play their role and make that fetus to mutate towards a gender? 2)in human anatomy penis and vagina , except the shape and functionality, are not different that much ! so as every thing else ! 3)due to that fetus being sexless times, a man has nipples, and woman got immature prostates ! are all of these generally ok?

i was start researching towards genetics and homosexuality and was wondering that either these claims are scientifically valid or not ! please say why if its a false claim and non valid evidence thanks "sexually differentiated behaviors are organized during early life by an irreversible action of sex steroids" http://www.morganclaypool.com/doi/abs/10.4199/C00064ED1V01Y201208DBR008?journalCode=dbr& "A linkage between DNA markers on the X chromosome and male sexual orientation" http://science.sciencemag.org/content/261/5119/321.abstract "Homosexuality may be caused by chemical modifications to DNA" http://www.sciencemag.org/news/2015/10/homosexuality-may-be-caused-chemical-modifications-dna "Homosexual orientation in twins: A report on 61 pairs and three triplet sets These findings are interpreted as supporting the argument for a biological basis in sexual orientation. supporting the argument for a biological basis in sexual orientation" http://link.springer.com/article/10.1007/BF01541765 "A difference in hypothalamic structure between heterosexual and homosexual men" http://science.sciencemag.org/conte...ract?sid=a3ac9da2-15b4-4cd7-9a16-1f08a2fdd62f “sexual attraction is influenced by genetic factors”, “heritable basis to male and female sexual orientation”, “found genetic influences on female sexual orientation as measured via attractions” http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0021982#pone-0021982-t001 “PET and MRI show differences in cerebral asymmetry and functional connectivity between homo- and heterosexual subjects” http://www.pnas.org/content/105/27/9403.short https://en.wikipedia.org/wiki/Xq28 http://science.sciencemag.org/content/285/5429/803.full http://www.dailymail.co.uk/sciencet...-Scientists-predict-gay-70-cent-accuracy.html
