Live from the BBC, the naked scientists.

Hello this week we're putting the X into sex because we're looking at the science of the X chromosome and diseases that are related to it.

And that's from the Sanger Institute, Dr. Mark Ross.

Hi Mark, Mark.

Hi, Chris.

So if you have any questions about things like baldness,

color blindness, hemophilia or muscular dystrophy,

those are all problems related to the X chromosome

and we'll be talking a bit about that later,

then call now.

08459, 25, 2000 is our phone number, the text number 076, 20, 1960, or email me, Chris

at naked scientist.com.

We're also going to be using the power of molecular biology or genetics to ask who's eating who beneath the ground because it's very easy to look on the surface and see animals eating each other and work out what's called a food web.

But how do you do that for animals that live out of sight,

out of mind and below the ground? Well Michael Traugot from the University of Cardiff is here to tell

us how he's using the science of molecular biology. Good evening Michael.

Hi Chris. To evening, Michael.

Hi, Chris, to do just that.

So they're here to take your questions this evening and talk about anything to do with genetics in general.

You just have to phone in, as I say, that number.

08559.
