Step into the world of Mendelian genetics, where the foundational principles of inheritance were first discovered by Gregor Mendel through his meticulous experiments with pea plants. This quiz will challenge your understanding of key concepts such as dominant and recessive traits, Punnett squares, and the laws of segregation and independent assortment. Let’s see how well you grasp the basics of genetic inheritance!
We recommend that you do not leave the page that you are taking this quiz in. Stay honest 🙂
