"what can be concluded from research examining freud's theory of sexual orientation? "

What can be concluded from research examining Freud's theory of sexual orientation is that no particular family life pattern is associated with developing a heterosexual or same-gender orientation. 
So, regardless of the fact whether the parents are heterosexual or homosexual, the child will not develop sexual affinities towards a certain gender just because of its parents' sexual preferences. It has to do with his or her own personal feelings, the society around them, media, etc.
