Homosexuality

This YouTube video explores the realm of homosexuality in twins. There are two cases presented: fraternal twins and identical twins. Adam and Jared are the fraternal twins, and Greg and Steve are identical twins. Just some bullet points that I gathered from watching the video:

• Adam’s behavior is called childhood gender nonconformity, where a child’s behaviors are more typical of the opposite sex. Extreme childhood gender nonconformity eventually leads to being gay.

• The environment in the womb is important (Hmmm… “environment in the womb” …is that nature or nurture?)

• Rat experiment – the hormones that you are exposed to after birth affects behavior (gave female rat an injection of testosterone, and rat became more manly)

• More older brothers a man has, the greater likelihood that is he gay (older brother affects boy only if boy is right-handed – Hmmm…what do you think about this?)
