One Gene Determines Ovaries or Testes =- and Back Again

arguably the best science reporting blog on the Internet, relates an
interesting story about gonads.
"As embryos, our gonads aren't specific to either gender. Their
default course is a female one, but they can be diverted through the
action of a gene called SRY that sits on the Y chromosome. SRY
activates another gene called Sox9, which sets off a chain reaction of
flicked genetic switches. The result is that premature gonads develop
into testes. Without SRY or Sox9, you get ovaries instead.
"But Henriette Uhlenhaut from the European Molecular Biology
Laboratory has found that this story is woefully incomplete. Maleness
isn't just forced onto developing gonads by the actions of SRY - it's
permanently kept at bay by another gene called FOXL2."
Please read the blog for the full story.

In short, and in direct contradiction to what the Bible teaches, we're
all born to be female. That one gene determines whether we stay that
way.

This "scale of gender" which runs almost uninterrupted between male
and female is something homophobes are too fundamentally stupid to
grasp and why this brain-dead dickhead got exactly what he deserved
when he went up against Rachel Maddow:
