| Trait | A characteristic that an organism that can pass on to its offspring through its genes |
| Genetics | The scientific study of heredity |
| Fertilization | The joining of a sperm and an egg |
| Purebred | The offspring of many generations that have the same traits |
| Gene | The set of information that controls a trait; a segment of DNA on a chromosome that codes for a specific trait |
| Alleles | The different forms of a gene |
| Dominant Alleles | An allele whose trait always show up in the organism when the allele is present |
| Recessive Alleles | An allele that is masked when a dominant allele is present |
| Hybrid | An organism that has two different alleles for a trait; an organism that is heterozygous for a particular trait |
| Probability | A number that describes how likely it is that an event will occur |
| Punnet Square | A chart that shows all the possible combinations of alleles that can result from a genetic cross |
| Phenotype | An organism's physical appearance, or visible traits |
| Genotype | An organism's genetic make up, or allele combinations |
| Homozygous | Having 2 identical alleles for a trait |
| Heterozygous | Having 2 different alleles for a trait |
| Codominance | A condition in which neither of 2 alleles of a gene is dominant or recessive |
