BIOL239 Chapter Notes -Gregor Mendel, Mendelian Inheritance, Stamen
Document Summary
Laid the foundation for the study of genetics. His ideas were published in 1866 under the title experiments in plant. His experiments on pea plants made it clear how traits are inherited. Easily grown in experimental gardens or pots. Contains both male and female sex organs. The male sex organ is the anther which produce sperm-containing pollen. The female organ is the ovary which produces eggs. Pea reproduction is peculiar in that the flower petals close down tightly which prevent any pollen grains from entering or leaving the plant. Pea plants self fertalize because of this restriction of incoming and outgoing pollen grains. These pea plants are highly inbred and display very little genetic variation from one generation to the next. Because of this uniformity such strains are known as true-breeding. Mendel cross-fertilized tall and dwarf plants to investigate how height was inherited.
