Morgan, Mendelian Heredity

In this book, geneticist T. H. Morgan and his colleagues proposed a gene-based alternative to Darwin’s mechanism of evolution. He and his colleagues at Columbia University in New York bred common fruit flies by the thousands—until a visible mutant was produced. They then bred that mutant with both normal flies and other mutants to see how traits were inherited over many generations. To their surprise, they found inheritance patterns predicted by Gregor Mendel’s theory of 1865.
