Gregor Mendel was an Austrian monk who in the 19th century worked out the basic laws of inheritance, even before the term "gene" had been coined. In his monastery garden, Mendel performed thousands of crosses with garden peas. Mendel explained his results by describing two laws of inheritance that introduced the idea of dominant and recessive traits.

Narration



Gregor Mendel, the Austrian monk laboring away in his garden in what is now Czechoslovakia with his pea plants, worked in relative unknown obscurity. [But he] did publish his results in 1865, showing that in fact you could model the inheritance of certain characteristics, such as wrinkled or smooth, by simple mathematical principles. It took another 35 years for his work to be rediscovered, but it provides the real fundamentals of understanding the genetic basis of inheritance, namely dominant and recessive traits upon which we now build much of human genetics.
