X and Y Chromosomes

I'm posting this because I just thought it was so cool. I know about the whole XX - XY boy - girl thing but I didn't realize that one of my Xs came from my grandmother on my Dads side... cool.

Each person normally has one pair of sex chromosomes in each cell. Females have two X chromosomes, while males have one X and one Y chromosome. Both males and females retain one of their mother's X chromosomes, and females retain their second X chromosome from their father. Since the father retains his X chromosome from his mother, a human female has one X chromosome from her paternal grandmother, and one X chromosome from her mother.

Moving...

Ok, so first of all, I'm not going to do my lead testing myself. Waaaaaay too expensive.
The equipment rental would have cost me thousands for one day. So I will send it to Jennifer Taggart at The Smart Mama and she will do it for me for a much more reasonable cost.

In other news, we moved this weekend. I forgot what a colossal pain it is to move. Holy Frijolé we collect a lot of stuff! I think it's healthy to move every other year just so you can purge all the junk. Or, well, better yet, just pretend you are going to move and clean out every corner.

So we had an internet-free weekend. It was strange. We went outside and moved plants around, climbed stairs and shifted boxes, not once thinking about e-mail... It was like... like... like the old days way back in the 90s before I spent my day in front of a computer plugged into the world. It's raining now or I would go back outside and play.

Just as well I suppose, I have a lot of catching up to do.

Have a successful day.
