Is it possible to order posts by two meta values?

Hopefully this is a reasonably straightforward question!

Is it possible to order posts, on the front-end of my WP install, by two meta values?

I have a meta key called genus and another called species. I’d like to sort firstly by genus (ASC), then species (ASC).

Thanks in advance,

AFAIK, you can’t do it using a meta query. Check this example, does what you want.
