    Study Notes

    Medical Genetics

    • Genetics is a part of biology that studies genes, heredity, and genetic variation in living organisms.

    Definition of Medical Genetics

    • Medical genetics is the application of genetic principles to medical practice, including:
      • Studies of inheritance
      • Mapping disease genes
      • Diagnosis and treatment
      • Genetic counseling

    History of Genetics

    • 1859: Charles Darwin published "The Origin of Species", which describes the theory of evolution by natural selection.
    • 1866: Gregor Mendel published "Experiments in Plant Hybridization", which lays out the basic theory of genetics.
    • 1900: The study of genetics was revived.
    • 1944: Oswald Avery, Colin MacLeod, and Maclyn McCarty showed that DNA can transform bacteria, demonstrating that DNA is the hereditary material.
    • A. Fisher started the study of quantitative genetics by partitioning phenotypic variance into a genetic and an environmental component.
    • Peptides
    • Proteins
    • Domains
    • Metabolites
    • Signaling

    Importance of the Genome

    • The genome provides valuable information about an organism.
