At least to me. I have no idea if I'll actually get to the point of conclusions/profoundness/or even slightly humorous with this post, but I'm rather fascinated with this subject, and feel the need to ramble.
About what you ask?
(yes, I considered titling this post channeling my inner vampire, but then someone would think it was a twilight post, and decide not to read it just for that fact.)
More specifically, blood types.
First, a little biology lesson.
Most of you know there are 4 types of blood: O, A, B, and AB. Type is determined by antigens present on the blood cells. If you are type A, you have a antigens. B has b antigens. AB has both, and O has none at all.
Then there's the +/- part. Since the vast majority of my readers all share the same blood type as me, I won't go into much detail about the rh factor. In really lame terms (as apposed to layman's), if you have - blood, your body tries to kill your offspring. So - blood is lame, and should not be passed down to future generations. Fortunately, it's also way more rare.
Why is this occupying so much of my thoughts lately?
You see, in my little family of 5, we have 5 different blood types. Seriously. Here's the run down:
Lil' flower: AB-
At first I was a bit dismayed at this fact. I thought that none of us could donate blood to each other if needed. After a bit of research, I found out I was wrong. We've got some lucky people, and some not so lucky people.
I can give blood to my two AB kids. Hubby would be able to give blood to all three kids, but due to that little -, can give only to Buddy (stupid -. I really hate that rh thing). In fact, anyone in the family can give Buddy blood. No one can give blood to Girly-Lou. Or me or Hubby.
Our whole family has relatively rare blood. Most of the world is O+ or A+. Lil' Flower has the rarest blood type in the world. According to Wikipedia, only .6% of the nation shares her blood. Girly-Lou has the second rarest, with 1.5%. Then Buddy with 3.4%, and me, with 6.3%. Hubby is downright common in comparison with the rest of us with 8.5%.
Something else, because of Hubby's type and my type, we could have offspring with any possible combination of blood type, including O (O is a recessive gene, so both of us could carry it). So future offspring could have any kind of blood.
My conclusions? I've got none. But it's fascinating to me all the different combinations in my family.
How about you? Do you know what's in your family? Do you care, or is this post nothing but my inner geek breaking free?
