| Gregor Mendel | Father of Modern Genetics |
| Pea Plant | Mendel's organism of choice |
| Pure Breeding | Always produce offspring like themselves |
| P | Parental Generation |
| F1 | First Fillial Generation |
| F2 | Second Fillial Generation |
| Principle of Dominance and Recessiveness | One "factor" will mask the other |
| Principle of Segregation | At gamete formation, the two "factors" for a trait segregate from each other |
| Molecular Genetics | The study of the structure and function of chromosomes and genes |
| Alleles | Contrasting forms of a gene |
| Monohybrid Cross | involves the inheritance of only one trait |
| Capital letters | dominant traits |
| Lowercase letters | recessive traits |
| Principle of Independent Assortment | "factors" for different traits are distributed to the gametes independent of one another |
| Test Cross | Unknown genotype individual crossed with a homozygous recessive |
| Incomplete Dominance | when two or more alleles influence a trait resulting in an intermediate trait |
| Codominance | Both alleles are expressed equally, no blending |
| Heredity | The transmission of traits from parents to offspring |
| Pure breeding | Produced by self-pollination |
| To work genetics problems | Make a key of the trait |
