      - • Effects of nutrients on genes
      - • Studying aspects of diet and the role of nutrients in gene expression
  - - - • How does a person's genetic background affect their diet
      - • Studying genetic variation, snps (single nucleotide polymorphisms) and how the body responds to a given nutrient/diet
      - • The human body has DNA that influences human development
      - • DNA is genetic material that has 4 variations, namely adenine, guanine, cytosine, and thymine
      - • A collection of components that have a specific function is called a gene, which influences health characteristics and the body's response to various nutrients

    - - Some of the more common single-gene disorders include cystic fibrosis, hemochromatosis, Tay-Sachs, and sickle cell anemia
      - caused by DNA changes in one particular gene, and often have predictable inheritance patterns.
    - - Multifactorial disorders involve variations in multiple genes, often coupled with environmental causes. Polygenic disorder caused by the combined action of more than one gene.
    - - refers to a group of disorders that affect the mitochondria, which are tiny compartments that are present in almost every cell of the body. The mitochondria's main function is to produce energy.
- - - - cross between two individuals, but with one different trait.
