Blood–what’s your type? November 11, 2005
My husband and I picked up the results of the blood typing tests on our sons Dylan and Lennon at the clinic this afternoon and learned that Dylan is AB+ and Lennon is A+. That’s to be expected I guess because blood type is inherited and I’m AB+ while my husband believes (he’s not sure) he is B+.
We had the tests done on our children because we thought it would be handy information to have.
I wanted to learn more about blood types so I looked it up on the Internet and found out that a person has two blood alleles, one each from the biological parents. A tutorial on the University of Arizona biology project website said “an allele is one of several different forms of genetic information present in our DNA at a specific location on a specific chromosome.”
There are three different alleles for blood types: A, B, and O. It was Austrian scientist Karl Landsteiner who classified blood according to the distinct differences he found when he examined samples under a microscope.
