Mendelian Genetics

by Tarrell Kurtz-Taylor

Gregor Mendel

Gregor Mendel was an Austrian monk who discovered the basic principles of heredity through experiments in his garden. Mendel's observations became the foundation of modern genetics and the study of heredity, and he is widely considered a pioneer in the field of genetics. He cross-pollinated tall pea plants with short ones and wrinkled pea plants with smooth. This is basically how he discovered genetics.

The Punnett Square

The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
