| The passing of characters from parents to offspring. | Heredity |
| Theb branch of biology that focusues on heredity. | genetics |
| is a cross that involves one pair of contrasting traits | monohybrid cross |
| describes organisms or genotype that are homozygous for a specific traits and thus always produces offspring that have the same phenotype for that trait | true-breeding |
| Parental generation, the first two indiviauls that mate in a genetic cross | P. Generation |
| the first generation offspring obtained from an experimental cross of two organisms | F1 Generation |
| the second generation of offspring, btained from an experimental crosss of two organsms the offspring of the F1 generation | F2 Generaion |
| one of the alternative forms of a gene that governs a characterics such as hair color | Allele |
| the expressed form of the character | dominate |
| the trait that was not expressed when the dominate form of the character was present | recessive |
| indiciduals are the same | homozygous |
| individual has for a character | genotype |
| the physical apperance of a character | phenotype |
| the first law | law of segregation |
| states that the allles of diffrent genes seperate independently of one another | law of independent assorsment |
| is the diagram that pridicts the outcome | punnet square |
| an individuals whose phenotype is domiante | test cross |
| is the liklihood that a specific event will occur | probalility |
| a family history | pediagree |
| allele is located only on the X and Y chromosome | sex-linked genes |
| when seeral genes influance a chrarcter | polygentic inherretence |
| displays a phenotype that is intermediate between the two parents | incomplete dominace |
| genes with three or more alleles | multiple alleles |
| both forms of the characters are displayed | codomiance |
