Science is a process of deriving facts about ourselves and about the world, further helping us to evolve and grow. Facts are hard to argue with and they separate the nonsense in our everyday lives from the reality.
When we’re young, we’re forced to sit through numerous science classes in school, in the hopes that we’ll become well-rounded and informed students. While some of us may or may not acquire much knowledge that we’ll remember from these classes, others learn a great deal. Just ask the girl in the following story whose life was changed after one routine biology lesson…
California State University San Bernardino
During a biology class at California State University San Bernardino, Professor Lisa Anderson was teaching her students about genealogy and tracking parentage. Genealogy, also known as family history, is the study of families and the tracing of their lineages and history.
While science class can be boring for some students, Professor Anderson tried to make them more interesting by getting the students involved. She did this by having each of them create a Punnett square, which is a chart showing the probability of inheriting certain traits from their parents…
Most of the students never did anything like this before, but they weren’t expecting to discover anything groundbreaking. If anything, they were going about the motions to pass Professor Anderson’s class.
One of the students in the class that day was 19-year-old Anya Hettich. She took to Twitter on February 21 to share what happened in class that day. “So on Monday we’re discussing blood types and this girl was trying to figure out why her blood type didn’t make sense on her Punnett square.” The girl seemed to be having trouble with it so the Professor stepped in to help…
She Couldn’t Possibly Have Type AB Blood
The student told the Professor that her dad’s blood type was type O and her mom was type A. When asked what her blood type was, she said it was AB. The professor knew immediately that this wasn’t possible, as anyone who understands Punnett squares knows that this doesn’t make sense.
Blood Is An Inherited Trait
She explained to the student that blood type is an inherited trait, which means that the blood type of your parents directly impacts what your blood type is. When inheriting genes, we inherit one gene from our mother and one from our father. Basically, you have two alleles, which are alternative forms of a gene…
Dominant And Recessive Genes
Furthermore, some genes are dominant and some are recessive: while dominant alleles will mask recessive alleles. Then, there’s phenotypes and genotypes, with a genotype referring to the gene a person inherits, while the phenotype refers to how it appears physically.
Determining Your Child’s Blood Type
The Punnett square explains this, but showing that if you know the blood type of two individuals, you can easily predict the possible blood types of their children. Professor Anderson insisted that either the student’s blood type was wrong, or one of her parents was wrong…
Various Punnett Squares
In an attempt to help the student, Professor Anderson drew out a few Punnett square diagrams to show that someone must have been mistaken about their blood type. Either that or something was drawn incorrectly or reported incorrectly from the lab.
Something Wasn’t Right
Still, the student persisted that she wasn’t wrong on the blood types and was confident that it was the professor’s mistake and there was something wrong with her diagram. Many students know that these instances are certainly possible where the professor makes a mistake, so Professor Anderson drew one last Punnett square…
The Diagram Doesn’t Lie
Again, the results were the same, making it impossible for a daughter of two parents with blood types O and A to have AB blood. Being that the A and B genes are dominant and the O gene is recessive if an O gene is paired with an A gene, the blood type will be A.
Impossible For Her To Have AB Blood
The A blood type only has the A antigen and the B blood type only has the B antigen. The AB blood type has both A and B antigens and the O blood type has neither A nor B antigen. It made absolutely no sense how the student’s blood was AB, it is only possible for it to be A…
It Wasn’t Making Any Sense
Upon the student’s insistence that the professor was wrong, Anderson decided to talk to the girl’s parents to double check the blood types to make sure the information was correct. That’s when a groundbreaking discovery was made.
The following day, the student came to class with some news that she decided to not only share with her professor, but with her peers as well. During class, everyone found out the truth about their classmate. It turns out, Professor Anderson was definitely correct and the student learned something beyond the assignment. Apparently, the young woman learned that her mother had an affair with a man who wasn’t her husband…
Hiding The Affair
“This girl is ballsy, lemma tell ya…She announces it to the entire class of 243 people.” We could only imagine that the girl’s reaction to learning this information and how difficult it was for her father to learn this. And to think, this all happened because of a simple science experiment during class.
A Family Torn Apart
The reality is, science is never simple. It’s eye-opening and gives you great insight into your life and the life of your family members. As far as what wound up happening with the girl’s parents…
The Importance Of Knowing Your Blood Type
The news was ultimately too much for the family to handle. The girl’s parents wound up getting a divorce. This story demonstrates how important it is to know your own blood type. Being that our immune system is trained to recognize foreign substances in our body, unfamiliar antigens can cause our body to have a reaction in which it tries to destroy any new and unfamiliar cells.
How To Learn Your Blood Type
This is why it’s vital when a person receives blood, that the receiver and the donor have compatible blood. To learn your blood type, the simplest way is to call your doctor and see if it’s been documented when you’ve previously drawn blood. But if it hasn’t been…
You can make an appointment with your doctor, go to your local clinic, or you can do the Punnett square at home. But, only if you know both of your parents’ blood types with certainty. Another option is to buy a blood typing kit if you don’t want to go to your doctor or donate blood.
Blood Typing Kit
These home test kits can be purchased online or at some pharmacies for as little as $10. You will have to prick your own finger, then add a little blood to each patch. Once you’ve completed the test, you can look up your blood type using the kit instructions.
