Uhm…my bad. I forgot that I’d planned on doing a blog about forensics on the last Friday of the month. I blanked that out last Friday. I blame it on the cough medicine. But…since I am the owner, curator, writer, and chief bottle washer of this blog, I get to change the rules! So now we’re going to do forensics on the FIRST Friday.
Today, I’m going to talk a little about how forensics work in the Penumbra world–specifically, about vampires, DNA, and blood typing. From SEASON OF THE WITCH, and Sade’s POV:
If people had known about vampires back in the day, there would have been no need to develop DNA testing. A vampire’s palate can’t be fooled. Not when it comes to blood and genetic typing. Her godfather, Mathias, knew from the barest taste of her blood that his accountant, William Marquis, was her father. That her mother, Tracie, had been the mistress of King Oberon at the time of her birth didn’t help matters. Of course, the King and Queen of Glitter Land weren’t satisfied with the outcome. Oberon and Titania, the most royal of the royal Seelie Court. Faeries. Sade’s life would be so much simpler without the fae mucking about in it.
We won’t mention how Mathias came to taste Sade’s blood when she was a baby. He claims it was for protection. I know it’s because he’s a control freak. Shhh. 😉
Anyway, having “worked” a few crime scenes back in the day, forensics fascinate me. There are whole classes on blood–blood splatter, blood typing, blood testing (for drugs and alcohol). And maybe because I’m adopted and had to bow out of those simple DNA tests in biology (there was one I still remember about determining eye color–my dad’s were brown, my mother’s green, and my brother’s green–mine are blue…hrmmmm) because I had no bloodlines to compare, I find the study interesting. Positive and negative. A, B. AB, O… You can follow THIS LINK for a fairly easy to understand overview and population clusters. And THIS LINK discusses blood donor compatibility and genetics.
But what does this have to do with vampires in the world of Penumbra? Vampires are blood snobs. Type O positive (O+) is like the beer of bloods, with O- like craft beers. The majority of humans have O+ blood pumping in their veins. Curious as to what would be the Dom Perignon of blood to a vampire? AB-. That’s the rarest blood type. And no, I wouldn’t do that to Sade. 😉 Despite her sterling qualities, she’s plain ol’ O negative. Hey, I had to give her a bit of flavor.
By now, y’all are probably sitting out there wondering how warped I am to sit here thinking about this stuff. I confess, I do. The forensics behind my books might never appear in print, beyond generalizations, but to me, they make the world more real…and realistic. As a reader, I appreciate a writer who understands the intricacies of their world. As a writer, I’m more comfortable if I know the…well, for lack of a better word, the physics of the world I’ve created.
So, happy first Friday! Have a great weekend. Stay warm. Read books. Watch movies. And come visit on Monday with my special guest, Cathy Tully.
