Plant research has often been done with plants. In genetics, the breeding of pea plants allowed Gregor Mendel to derive the basic laws governing inheritance, and examination of chromosomes in maize allowed Barbara McClintock to demonstrate their connection to inherited traits. The plant "Arabidopsis thaliana" is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. NASA predicts that space stations or space colonies will one day rely on plants for life support. Ancient trees are revered and many are famous. Tree rings themselves are an important method of dating in archeology,
Adoption detective their parents is information that has been used since prehistoric times to improve crop plants and animals through selective breeding. The biological science of genetics, which began with the work of Gregor Mendel in the mid-nineteenth century, seeks to understand the process of inheritance and the physical basis for heredity in our DNA. What is known about human traits inherited through patients' families can save their lives—that is why gathering a person's complete and accurate medical family history is extremely important even as genetic medicine continues to explain more diseases. Many advances in biological medical science are anticipated in the
