|---|---|
| The passing of characters from parents to offspring. | heredity |
| The branch of biology that focuses on heredity. | genetics |
| is a cross that involves one pair of contrasting traits | Monohybird cross |
| describes organisms or genotypes that are homozygous for a specific trait and thus always produces offspring that have the same phenotype for that trait | True-Breeding |
| Parental generation, the first two indiviuals that mate in a gentic cross | P. Generation |
| the first generation offspring obtained from an experimental cross of two organisms | F1 Generation |
| the second generation of offspring, obtained from an experimental cross of two organisms; the offspring of the F1 generation | F2 Generation |
| one of the alternative forms of a gene that governs a characteristic such as hair color | Allele |
| the expressed form of the character | dominant |
| The trait that was not expressed when the dominant form of the character was present. | Recessive |
| individuals are the same | homozygous |
| individuals has for a character | genotype |
| The physical apperance of a character | phenotype |
| the first law | law of segregation |
| states that the alleles of diffrent genes separate independently of one another. | law of independent assortment |
| is the diagram that pridicts the outcome | Punnet Square |
| an individuals whose phenotype is dominat | test cross |
| is the likelihood that a specific event will occur | Probability |
| a family history | pediagree |
| allele is located only onon the X and Y chromosome. | sex-linked genes |
| when seeral gnes influance a character | polygenic inhertance |
| displays a phenotype that is intermediate between the two parents. | incomplete dominance |
| genes with threee or more alleles | multiple alleles |
| both forms of the characters are displayed. | codomiance |
