| Heredity | the passage of genetic information from parents to offspring |
| trait | feature or characteristic than can be passed on genetically from one generation to the next |
| phenotype | the physical appearance of an organism. |
| genotype | the genetic information that determines the phenotype |
| gene | a segment of DNA that determines or helps to determine a trait. |
| hybrid | the offspring of genetically different parents. |
| DNA | a big molecule shaped like a spiral staircase that contains genetic information |
| homozgous | having two identical alleles for a trait |
| heteroszygous | having two different alleles for a trait |
| dominant allele | genetic information that always ends up being seen in the phenotype no matter what other allele it is pared with |
| recessive allele | genetic information that only shows up in the phenotype when it is pared with another recessive allele for this trait |
