| Genetic | the study of heredity |
| Alleles | The physical evidence of a gene |
| Heredity | the passing of genetic material from parent to offspring |
| Fertilization | the union of a male and female gamete to form a zygote |
| Dominant Allele | The allele that physically appear in an organism |
| Recessive Allele | The hidden allele that does not appear |
| Codominance | Both traits are dominant and physically appear |
| Heterozygous | having two different alleles Example Bb, Tt |

| Asexual reproduction | One parent. Parent and offspring have same genetic makeup |
| Sexual reproduction | Two Parents each contribute a sex cell to the new organism |
| Phenotype | Physical appearance of a gene |
| Genotype | The letter representation of a gene |
| Trait | a characteristic expressed by a gene (ex. hair color, leaf shape, eye color, etc.) |
| Clone | an exact copy of cells produced asexually |
| Genes | one segment of DNA from parents |
