Final answer:
Statistically, children raised by same-sex parents are most likely to grow up to be heterosexual. Sexual orientation awareness typically develops in individuals between middle childhood and early adolescence, and parental sexual orientation does not determine a child's eventual sexual orientation. So none of them are true.
Step-by-step explanation:
Statistically, when considering the sexual orientation of children raised by same-sex parents, research has found no quantifiable data to support the notion that sexual orientation is determined by the parent's sexual orientation. In the context of a study analyzing 81 parenting studies, sociologists Biblarz and Stacey (2010) reported that children of lesbian couples tend to have slightly lower rates of behavioral problems and higher rates of self-esteem, but this does not translate into a predetermined sexual orientation outcome for the children. The majority of children, irrespective of their parents' sexual orientation, grow up to be heterosexual, which is a reflection of the larger statistical reality that between 90% to 97% of the population identifies as heterosexual.
Additionally, current scientific understanding from the American Psychological Association (2008) suggests that individuals are usually aware of their sexual orientation between middle childhood and early adolescence, indicating that awareness of sexual orientation is a personal realization that may or may not converge with familial influences or parental orientation. It is also important to recognize the role that historical norms and societal expectations play in the development and recognition of sexual orientation.
