Aside from developing the single-lens microscope, he also discovered living organisms particularly the protozoa and
bacteria from rainwater.
Anton Van Leeuwenhook
Published Experiments in Plant
Hybridization
Gregor Mendel

Friedrich Miescher
rediscovered mendel’s work
■ Carl Correns
■ Hugo de Vries
■ Erich von Tschermak
Discovered that alkaptonuria, a
human disease has a genetic
basis.
Archibald Garrod
Hypothesized that the behavior of chromosomes during meiosis,
thus leading to the discovery that
genes are located on chromosomes
Walter Sutton
Coined the term “gene”

genes; Coined the term “epistasis”; coined the word “genetics”

discovered the science
of genetic linkage
