| heredity | information that is passed down from parents to offspring |
| incomplete dominance | alleles that are both dominant but blend in the offspring |
| allele | two versions of a trait, one from mom and one from dad |
| genome | all of the genes present that make up an organism |
| phenotype | the physical appearance of a trait in an offspring |
| genotype | the gene combination of a trait |
| dominant | a trait that is always seen if present in a genotype, this gene will always hide a recessive gene |
| recessive | a trait that is hidden by a dominant gene. This type of trait will only be seen if two of them exist in the genotype |
| Mendel | father of genetics who bred pea plants to learn about heredity |
| homozygous dominant | two dominant genes in a genotype. Can be referred to a pure bred dominant(TT) |
| heterozygous | two different genes in a genotype, one dominant and one recessive (Tt). Can be called hybrid. |
| Law of Segregation | Mendel's law that states that genes separate during gamete production (meiosis) |
| Law of Independent assortment | Mendel's law that states that genes will combine with other genes during fertilization, randomly and independently of other genes. |
| sex linked traits | gene that is carried on the sex chromosomes such as the X and Y. Examples are colorblindness, baldness and hemophilia, most of these disorders are gender specific |
| co-dominant | Alleles that are both dominant and are both seen in the phenotype. |
| homozygous recessive | tow recessive genes in a genotype, can be referred to a pure bred recessive (tt) |
