  3. A ________________ is the genetic make-up of an organism. • phenotype • genotype • letter • number Vocab 1

  4. An example of a phenotype: • Eye color • genotype • Shirt color • Bb Vocab 2

  5. The parts that make up a gene are called: • Parents • Animals • Plants • Alleles Vocab 3

  6. An example of the homozygous genotype: • Hh • Bb • bb • hH Vocab 4

  7. The study of heredity: • genetics • biology • science • hereditology Vocab 5

  8. When two or more genes affect a trait: • Multiple alleles • Incomplete dominance • Codominance • Polygenic inheritance Vocab 6

  9. A carrier has: • Multiple alleles • One dominant, one recessive • Codominance • Polygenic Inheritance Sex-Linked 1

  10. One example of a sex-linked trait is: • genotype • foot size • hair color • colorblindness Sex-Linked 2

  13. A person that has hemophilia has problems with: • Blood clotting • Blood cells • Fear of blood • Low hemoglobin Disorders 3

  14. The disorder that causes a person to have thick mucus in their lungs & intestines: • Down Syndrome • Hemophilia • Cystic Fibrosis • Sickle Cell Disease Disorders 4

  15. The first stage of cell division, before mitosis begins: • Interphase • Prophase • Metaphase • Cytokinesis Cell Division 1

  16. In mitosis, these fibers start to form during prophase: • String • Centrosome • Spindle • Nucleus Cell Division 2

  17. During which phase do the chromosomes line up in the middle of the cell? • Interphase • Metaphase • Anaphase • Cytokinesis Cell Division 3
