Genes
| Term | Definition |
|---|---|
| Genetics | Scientific study of hereditary |
| Trait | Characteristic that varies from one individual to another |
| Alleles | Different possibilities for each trait (each trait as two or more’) |
| Segregation | Two alleles for each trait separate when gamates form. |
| Independent assortment | Genes for different traits are inherited independently |
| Dominant | Masks the other trait, respresnted by capital |
| Recessive | Will only happen if dominant allele is not present. Lower case letter |
| Genotype | The genetic makeup of organism. Allele combo organism has. |
| Phenotype | Physical characteristic of organism, way it looks |
| Homozygous | Organism that has two identical alleles for trait |
| Heterozygous | Organism that has two different alleles for the same trait |
| Punnett square | Diagram shows gene combos from genetic crossing Used to calculate probability of trait |
| Incomplete dominance | One alleles is not completely dominant |
| Codminanace | Both alleles contribute to the phenotype of organism |
| Multiple alleles | Three or more alleles in same gene |
| Examples of multiple alleles | Coat color, blood type and hair color. |
| Polygenic trait | Trait by two or more genes |
