Homosexuality, Genetics or Preference Essay - 800 Words

Let us begin with a definition of homosexuality. Homosexuality refers to a sexual attraction and or behavior between people of the same sex.

If the twins were fraternal instead of identical, the percentage drops to 22%. The significant differences in these percentages show a genetic component to sexual orientation. Another scientific study from 2006 said that researchers have known for years that a mans likelihood of being gay rises with the number of older biological brothers, but the new study found that the so-called fraternal birth order effect persists even if gay men were raised away from their biological families. Anthony F. Bogaert, Ph.D., professor at Brock University, said The research suggests that the development of sexual orientation is influenced before birth.
