| alleles | different forms of the same gene |
| homozygous | when both alleles are the same |

| gametes have | 1 copy of a gene |
| a zygote has | 2 copies of a gene |
| genotype | the genes for a characteristic |
| phenotype | characteristic displayed due to a genotype |
| BB | is a homozygous genotype |
| Bb | is a heterozygous genotype |
| cc | is a recessive homozygous genotype |
| HH | is a homozygous dominant genotype |
