Biology Professor Accidentally Reveals This Girl’s Dad Is Not Her Dad, And Things Escalate Quickly
A biology student got an unexpected lesson recently, when she found out about her mother’s infidelity through a blood-type discussion given in class.
The biology class, given at California State University, was about the characteristics of blood-types and how they are passed down from generation to generation. They were practising using a Punnett square, which is a diagram that is used to predict an outcome of a particular cross or breeding experiment. The student was reportedly confused as to why her blood-type was AB when her mother’s was A and her father’s O. This is an impossible occurrence, as the A and B genes are dominant and the O gene is recessive. So, as in this example, if an O gene is paired with an A gene, the blood type will be A.
The teacher, sure there was a mistake somewhere, asked the student to go home and confirm that all blood-types were correct. She did, and came back with an incredible revelation that took incredible courage to tell to the entire class.
The entire episode was tweeted by her classmate in a thread that has gone wildly viral. Scroll down below to check it out for yourself, and let us know what you think in the comments!

I saw this somewhere a few days ago... Despite the story, I just couldn't help thinking about the fact that there's 243 people in a single class and the fact that somehow all those people never learned this in high school and are just finding this out in University.
Thers a show about this idea called "are you smarter than a fifth grader"

someone always told me... anything you do in the dark will always come to light... it makes sense now... sorry for her
My son texted one day asking my blood type. I told him B+. He said that his Dad had to be A- because he tested AB-. I said, well then that's what he has because I am 100% positive that he is your father. Then I thought, what if some poor kid in high school in a tiny town in MS discovered that his dad is not really his dad from science class in 10th grade? Well, that s**t really happens.
My dad grew up believing he was Metis and after doing a DNA test found out he's mostly Irish. Not a drop of Metis in him. He's so mad. Now the rest of us are getting the tests to find out who is really what. This is sad that the secret kept ended up with her parents divorcing, but also unfair of her mom to do that to her. Wow.
Most of the responses are saying how s****y biology is for this, but in reality it's the mother that's s****y... Don't cheat. What a concept!
Science and reality don't care about feelings. Hell, people, facts cannot be "s****y"....... Just true or false.

OH MY GOSH, my biology professor was in the same lecture, and it's his favorite story ever! He tells his classes this every year
JFC. Just goes to show that your dishonesty will come back to bite you eventually.
It was an awful way to find out, but better now than down the road. That mother is a white and a liar and she deserves to be dumped and divorced. I just hope the girl and her father can keep their relationship.
I mean to say, "a whore and a liar". Blasted autocorrect.

The tweets show the professor was a woman, so a different picture with the headline would have been better. Great story, though!
Just found a niece I never knew about because of AncestryDNA testing. She's a wonderful person.
Similar thing happened in my HS Biology class. Teacher had us bring in urine samples to observe under the microscope. One girl spotted something that wasn't in the literature to look for. Yep she was pregnant and the Teacher was the first one to inform her.
I hope that she stays close to the man who raised her, and that he has the maturity to not blame her.
Plot twist twist: all of that has really happened, but also the children were switched in the hospital when they were newborns.

I am AB+. My ex-wife is O-. My daughter insisted for years that she was O+. I told her that was impossible. She insisted. I said we could get a DNA test to settle this. She didn't want to, insisted that her mom would never have cheated on me, but still insisted she was O- despite that being an impossibility. Finally, she donated blood when she turned 18. Guess what? A-. She's probably mine. Science wins again.
The very reason these kind of experiments are no longer carried out in high schools in Australia.
Because cheating wives banned it? There is no moral system which in it is considered to be right.

getting divorced after 21 yrs from the fling... uh, unless it's still going on, let it go.
and send your stepbrother a bill. heehee.

We had a similar story from our biology school teacher - he was teaching about the ability to roll your tongue is a dominant trait, and a kid went home, found neither of his parents could roll their tongues, and that's when they had to confess he was adopted as a baby
Huh, remember learning that. I can and my parents can't, but I'm not adopted unless everyone is crazy good at keeping secrets!

All of those situations are bad but it's a shame those experiments were discontinued because of human lies and shenanigans.
I wouldn't mind finding out I have a different dad..... as long as the new one turns out to be really, really rich or royalty or something
I would just like to say that, even though the girl may or may not consider him her dad any more- some of us do have fathers/mothers/parents that are not biologically related to us. Obvi the lying didn't work out so well, but for those of us that do have parents that are not related to us by blood- it is still possible for some of us to consider them "real" family.
Truth will out. Always be truthful, or it will bite you in the butt.
"Biology is the major cause of broken homes." Well, yes. And not the bio class, either.
Maybe if the cheatin' whore had realized that her bowels can't get pregnant.

It's not necessary true. There are cases (but very very rare cases) of structural mutation. There was per example a japanese Child with Type 00 that had a biological mother with Type AB. So in biology there is no such thing as impossibility, because there might be a mutation. But the cases are rare enough that normaly a "cheating parent" is the better explanation. To the study about the japanese child, see: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1685204/

all one has to do is look in a mirror.. i have my dad's nose and my mom's eyes.
The eye color thing though...that one can trip you up. I have brown eyes, so does my son's father. Our son? Crystal blue eyes. In laws both had brown eyes. My mother has green eyes, her parents had blue eyes. My father his parents, all brown eyes. So eye color CAN skip generations!
This sort of lie/deception should be a punishable crime. Why are women allowed to get away with causing this kind of harm?
Perhaps.....but I saw this about once a year as a maternity nurse.

My dad isn't my biological dad, but he does have blue eyes and so do I. The blood type thing though...... I have no clue what his blood type is lol
Lots of gullible people on Bored Panda who will believe this story.
I'm glad for family resemblance...never any doubts, even as an angsty teen. Same with my kid.
Hey the photo should be of a FEMALE bio prof. The tweets says “she drew”! This is a chance to change assumptions that biology profs are all male.
Blood types are far easier genetics-wise. You have one single gene for blood type, but you have at least three for eye colour, that can interfere with each other or can mutate. Two light-eyed parents CAN have brown-eyed children. It's rare, but not impossible.

It's not like the persons involved can be identified from this.
