What research-based evidence suggests homosexuality may have a biological basis in some people??

What will be an ideal response?

ANSWER:
?Twin studies of identical and fraternal twins who are gay show a higher concordance rate for identical twins. Also, gay men have a greater number of older brothers, suggesting some mothers may become increasingly immune to prenatal male hormones, which may represent a different hormonal prenatal development for successive male fetuses.
