Final answer:
Sexuality is not solely genetically determined, as it is influenced by a combination of genetic, hormonal, developmental, social, and cultural factors.
Step-by-step explanation:
False. Unlike other human behaviors, sexuality is not solely genetically determined. Research has shown that sexual orientation has an underlying biological component, but it is influenced by a combination of genetic, hormonal, developmental, social, and cultural factors. For instance, studies have demonstrated gene-level contributions to sexual orientation, differences in brain structure and function among those with different sexual orientations, and even differences in basic body structure and function. While genetics plays a role, it is not the sole determinant of sexuality.
