I heard that women are not good at math. And, men are better at it than women. I also heard that women are better in English than mathematics. I know some women who are not good at math. I'm one of them I'm better in English. So, my question is is this true? Are men better in mathematics than women? Or, is this a myth? If so, why is that the case?

It recently occurred to me that I missed out on understanding this phenomena called chimerism.

I recall seeing a few specials back in August 2006 about Lydia Fairchild on ABC networks.

I didn't quite understand the big "theme" here, to explain how the kids share no genetic identity with their biological mother.

I have followed up recently on the story, reviewed the story, and it is still not making sense to me.

Does anyone have a website to share, which might show the pedigree for this phenomena?

Or, would anyone be willing to explain to me how Lydia Fairchild's haploid genome was swapped with someone else's genome?

The concept of "you are your own twin" would be made clear after testing both parents of Lydia, right? Or did I miss in the story that one parent (or both) were not available for genetic testing.

Thanks for your help!

Here is a link, in case you forgot the details regarding this story.
