    Study Notes

    Variation and Inheritance

    • Natural Selection maximizes the number of successful variations by favoring individuals with advantageous traits.
    • Genetic drift, mutation, and gene flow create diversity over succeeding generations.
    • Inheritance of variations occurs through the transmission of genetic information from one generation to the next through the germ cells (sperm and egg cells).
    • Figure 8.1 illustrates how genetic information is passed from one generation to the next, resulting in a diverse range of traits in succeeding generations.
    • Multicellular organisms, such as plants and animals, exhibit distinct variations among different individuals due to their complex genetic makeup.
