    • CHAPTER 11 Introduction to Genetics
    • Gregor Mendel
      • Austrian monk who worked with true-breeding pea plants
      • He cross-pollinated them
      Angela + Allie
    • Basics of What Mendel Learned
      • Genes  passed from parents to offspring
      • Dominant  allele that will show up
      • Recessive  allele that will not show up
      • Alleles separate independently
      Allie Presher
    • Phenotypes vs. Genotypes
      • Examples of phenotypes:
      • 1. Tall pea plants
      • 2. Brown hair in humans
      • Examples of genotypes:
      • 1. TT  homozygous
      • Tt  heterozygous
      • tt  homozygous
      2. BB Bb bb Allie Presher
    • Punnett Squares Punnett squares show the probability of possible outcomes of certain traits in organisms. Angela Nguyen
    • Incomplete Dominance and Codominance
      • Angela Nguyen
      Example of Incomplete Dominance: Example of Codominance:
    • Polygenic Traits
      • Controlled by two or more genes
        • Example:
          • Skin color in humans
      Angela Nguyen
    • Meiosis
      • Allie + Angela
    • Linked Genes
      • Genes that are on the same chromosome: they stay together
        • Example:
          • Black body and reduced bristles on fruit flies
