Hour Two:
The X Chromosome

What, deep down, makes a woman a woman? Sugar and spice and everything nice? Nope - unless you count the tiny amount of sugar that makes up the backbone of the DNA in the X chromosome.

You probably learned once that women have two X chromosomes, while men have one X and one Y. But can that microscopic difference really account for all the differences between the sexes - beyond the physical differences to the emotional, behavioral, and psychological differences? (and do all those differences actually exist, or are some of them just a product of society?)

On this hour of Science Friday, we'll talk about the X chromosome and what it does... and next week, we'll continue the conversation in this hour with a look at the Y chromosome.
