answered-by-expert Expert Answer
Homosexuality involves sexual and romantic attraction between members of the same sex or gender. Development of homosexual individuals depends not only on the germ cell of the father, but is also influenced by a combination of genetic, hormonal and social factors which determine sexual orientation. These factors include genes, prenatal hormones and brain structure.
