New genetic and reproductive technologies affect LGBTQI communities in exceptional ways.

Some of these are beneficial. For example, advances in assisted reproductive technologies enable a growing number of gay men and lesbians to become parents of biologically related children.

However, some advocates of reproductive cloning assert that gays and lesbians in particular should support it, because it would allow same-sex couples to have children that are genetically related only to a member of the couple, free of "external" DNA. Of course, such techniques do nothing to address the underlying issues of inequality and homophobia that plague society.

Genetic theories play as strong a role in shaping our social and individual identities as they do in shaping our families. Recent years have seen a resurgence of assumptions that complex human behaviors, including sexual orientation, are simply products of our genes. Though scientists have yet to find a genetic marker for homosexuality, many continue to try. Such genetic determinism and reductionism open the door to new forms of discrimination.
