CHAPTER TWO: Gregor Mendel and Dominant and Recessive Traits

This chapter deals with Gregor Mendel and the issue of dominant and recessive traits. While Charles Darwin's argument in favor of natural selection explained most of the available facts about heredity, there remained a few missing pieces that bothered him and his supporters. The second missing piece of Darwin's theory of natural selection was found by Gregor Mendel, an Australian monk. Details of Mendel's education and family life was provided. Working alone, Mendel analyzed thousands of seeds and plants. His data provided him with some interesting facts about heredity in peas. The rediscovery of Mendel's work, combined with the recent discoveries of microbiology, opened up a new area of scientific study. In 1909, Danish botanist W. L. Johannsen named Mendel's unit of heredity the gene, and the study of heredity became known as genetics.
