      • Does not mean that the individual will develop that condition
      • Genetic condition cannot be altered
        • Changing environmental factors, support, and treatment can help an individual live as healthy as possible

        • Y that is inherited = XY (male)
    • Genes
      • Made out of a substance called DNA
        • DNA has the biological instructions to create another life
      • Dominant genes only need to be passed by one parent in order for the condition to develop
      • Recessive genes need to be passed by both parents
    • Genetic factors that affect development
      • Predisposition diseases
        • Inherited genes that determine physical growth, development, health, and appearance
      • Susceptible diseases
        • An increased likelihood of acquiring a disease because of an individual's genetic makeup
      • Biological factors
        • The environment inside a mother's womb can have a dramatic influence on a  child's development
