| Scientific study of heredity | Genetics |
| A characteristic that can be passed from parent to offspring | Trait |
| Recieved same genetics fro | Purebred |
| An organism that recieves different forms if genetics traits from each parent | Hybrid |
| Dominent Allele | A form of gene that is fully expressed when two different alleles are present |
| Recesssive Allele | A form of gene that is not expressed when paired with a dominent allele |
| Sections of a Chromosome that code for a trait | Genes |
| A distinct form of a gene | Allele |
| States that the material of inheritance is carried by the genes in chromosomes | Chromosome theory of heredity |
| The genetic makeup of an organism | Genotype |
| Outward expression of the trait | phenotype |
| An organism in which the two alleles in a gene pair are identical | homozygous |
| An oraganism in which the two alleles for a particular trait are different | heterozygous |
| Mendel hypothesized that gene pairs seperate when gametes form | Law of Segregation |
| Mendel concluded that traits are inherited independently | Law of Independent Assortment |
| Dominent allele is expressed and recessive allele can be hidden | Law of Dominance |
| A grid for organizing genetic information | Punnet Square |
| A chart that shows how a trait and the genes that controls it are inherited within a family | Pedigree |
| An individual that carries a recessive trait that is not expressed | Carrier |
| Provides prospective parents with information about the possibilties of passing genetic disorders onto thier offspring | Genetic Counseling |
| heterozygous offspring show a phenotype that is in between the phenotypes of the two homozygous parents | Incomplete Dominance |
| Both alleles in heterozygote express themselves fully | Codominance |
| A trait controlled by two or more genes | Polygenic Trait |
| # or more alleles found in a population | Multiple Alleles |
| Occurs when a single gene affects more than one trait | Pleiotropy |
