| A | B |
|---|
| alleles | different forms of the same gene |
| dominant | gene that is expressed/stronger gene |
| recessive | only expressed when not masked by a dominant gene |
| homozygous | same |
| heterozygous | different |
| hybrid | mixed offspring |
| genotype | genetic makeup |
| phenotype | physical appearance |
| P generation | parents |
| F1 generation | offspring of parents |
| F2 generation | offspring of first generation |
| homologous chromosomes | identical pair of chromosomes |
| wild - type | allele that occurs w/ greatest frequency |
| cross | an animal or plant resulting from crossbreeding |
| punnett square | diagram used to predict outcomes |
| monohybrid cross | one trait crossed |
| dihybrid cross | two traits crossed |
| phenotypic ration | ratio of physical traits |
| Law of Segregation | alleles separate during meiosis |
| Law of Independent Assortment | one trait does not affect another |
| Law of Dominance | stronger gene expresses itself |
