Genetics
| Term | Definition |
|---|---|
| Allele | The different forms of a gene such as a dominant or recessive, represented by a letter. |
| Dominant Gene | Represented by a capital letter. |
| Recessive Gene | Represented by a lower case letter. |
| Sexual Reproduction | Two parents produce an offspring with a mix of traits from both parents. |
| Asexual Reproduction | One parent produces an offspring that is one exact copy of the parent. |
| Chromosome | Carries genetic information that controls inherited characteristics such as eye color. |
| Gene | A set of intructions for an inhereited trait found in a section of DNA. |
| Trait | The specific forms of a characteristic that are passed onto offspring through genes. |
| Heredity | The passing of traits from parents to offspring. |
| Homozygous (pure bred) | Two of the same alleles; both dominant or both recessives; RR or rr. |
| Heterozygous (Hybrid) | Two different alleles; one dominant with one recessive; Rr |
| Phenotype | The physical characteristic of a person (visible trait). |
| Genotype | The genetic makeup of allele combinations. |
| Dominant Allele | An allele whose trait is always visible when the allele is present. |
| Recessive Allele | |
| Genetics | The study of heredity. |
