Great discoveries in Genetics
A good priest who left his mark as a great scientist by exploring the miracle of heredity. A brilliant researcher, her work largely ignored by her male colleagues, until a revolutionary breakthrough. This is a spellbinding journey to find the common thread of molecules that define the biology of life. An unprecedented collaboration of scientific minds and willpower to solve the mystery of what makes us human. These are the greatest discoveries in the history of genetics.

1. Rules of Heredity (1850s)
Austrian monk and botanist Gregor Mendel discovers how genetic information is passed down through generations. In experiments performed on pea plants, he notices that characteristics of a plant’s offspring, such as height, exhibit recessive and dominant behavior. Mendel’s findings are ridiculed during his lifetime and he dies never knowing that he would come to be known as the “father of genetics.”2. Genes Are Located on Chromosomes (1910 – 1920s)
Thomas Hunt Morgan discovers that genes are located on chromosomes. Working on fruit flies, he concludes that certain traits are linked to gender and that those traits are probably carried on one of the sex chromosomes (X or Y). He hypothesizes that other genes are also carried on specific chromosomes. Using chromosome recombination, he and his students map the locations of genes on chromosomes. Morgan and his students write the seminal book The Mechanism of Mendelian Heredity.
