  7. homozygous
    individual that carris two copies of the same allele
  8. heterozygous
    an individual that carries two diffrent alleles
  9. dominant
    an allele that can hide the effects of a recessive allele
  10. recessive
    an allele that can be hidden by the effects of a dominant allele

  12. quantitative trait
    • traits which show a large range of phenotypes, and are polygenic
    • measure on a scale
  13. polygenic trait
    traits which are influenced by many genes
  14. heritability
    a measure of how much genetics influences a phenotype
  15. two different ways genes get messed up
    • random allignment
    • crossing over
  16. codominance
    shows both parents genotyes, neither dominant or recesive
  17. qualitive
