Article: Gene Regulation May Explain How Homosexuality Flourishes

[Ahso!]

This is interesting stuff.

The search for a "gay gene" may be off-target, new research finds. Another process called epigenetics that switches genes on and off may explain why homosexuality runs in families.

Epigenetics are heritable changes caused by factors other than DNA. Instead of traits getting passed down through the genes, epigenetic change happens because of the way genes are regulated, or turned on and off.
