|Abstract: ||The cause of homosexuality remains a hotly contested debate to this day. Although
the role of genetics has diminished over the past decade because of the
popularity of environmental influences, it continues to be a relevant correlative
possibility. Since its inception in the early 1990's from a study conducted by Dr.
Dean Hamer, the genetic locus Xq28 has become amongst one of the most important
genetic factors of sexual orientation. Subsequent studies attempting replication
have improved on the original experiment although the initial measures
and methods of experimentation may have biased the results of the findings.
Consequently, contention between advocates for and against Xq28 continues
over 15 years later with mounting evidence weakening the link of Xq28 and homosexuality.
Even though the majority of genetic discussion revolves around
Hamer’s original findings, more recent genetic markers have also now been
found which may show positive connections and provide the basis for further
