Punnett squares are widely used in biology to predict blood group inheritance. |
The biology professor had previously taught about the properties of blood types and how blood types are passed down from generation to generation. The students then used the Punnett square – a chart that predicts blood types – in the practical session.
However,A student was confused when she said that her blood type was AB but her mother's was A and her father's was O. This was an impossible result because according to the Punnett square, if a person with blood type O mates with a person with blood type A, the child will have blood type A.
The professor guessed that his student had mistaken her parents' blood types, so he asked her to go home and confirm. After further questioning, the student bravely announced to the whole class in the next class that all her blood types and her parents' were correct. Her mother had had an affair with her husband's brother to give birth to her.
NicknameAnya, one of the female student's classmates, revealed on Twitter that the female student's mother had hidden her husband and daughter for the past 21 years. After the truth was exposed, the couple is in the process of divorce.
