  1. The type of trait, or allele that, if present, will cause the trait
    Dominant
  2. The genetic makeup of an organism (the alleles that cause the trait)
    genotype
  3. When an individual has two different alleles for a particular trait
    Heterozygous
  4. The type of trait or allele that is hidden and of which there must be two copies in order for the trait to show
    recessive
  5. A description of the physical look or behavior of an organism
    Phenotype
  6. When an individual has two of the same alleles for a particualr trait
    Homozygous
  7. What do the letters along the side of the punnett square represent
    Parent Gametes
  8. What do the letters inside of the Punnett Squares represent
    Zygotes genotypes
  9. Two alleles for a trait separate when gametes are formed
    Law of Segregation
  10. instead of blending together, some traits will override other traits
    Law of Dominance
  11. During gamete formations genes for different traits separate independently from one another
    Law of Independent Assortment
  12. A person with curly hair and a person with straight hair have a child with wavy hair
    Codominance
  13. Skin color is different b/c of six different genes
    Polygenic
  14. Extra fingers is caused by a single gene that, if present, causes the disease
    Simple dominance
  15. Cystic fibrosis can only occur if both parents give the same allele
    Recessive inheritance
  16. Hemophila is caused by a gene that is found on the X chromosome
    Sex linked chromosome
  17. There are three alleles for blood types; every individual only recevies two
    multiple alleles
  18. Somatic Cell
    Body Cell
  19. Germ Cell
    Sex Cell (egg,sperm)
  20. What is the difference between a germ cell and a somatic cell mutation? Which can be passed on to offspring?
    Germ cell is the only mutation that can be passed on. Somatic only affects you
  21. Examples of chromosomal mutation
    • Trisomy
    • Monosomy
    • Down syndrome
  22. Examples of gene mutation
    • Color Blindness
    • Huntington
