Dear MEL Topic Readers,
No single gene associated with being gay
Homosexuality is not genetically determined,
a new study from nearly half a million people found. The genomes, the entire
genetic make-up, of the participants were scanned to find if there are any
specific genetic variants associated with homosexual behavior, but no clear link
was found between any specific gene and sexual behavior. In other words, there
is no single gay gene. Therefore, it is meaningless to conduct a genetic test
to find if a person is or potentially be gay.
Isn’t this a good study to prevent segregative
or discriminatory screening tests from being conducted for employment or
enrollment process? Finding a link between a particular gene and diseases will
help prevent or cure those diseases. But it also seems important to find no link
to avoid prejudice and mistreatment.
Enjoy reading the article and learn about a
study that has found no link between a suspected cause and behavior.
