| adaptation | traits that enable organisms to survive in certain environments |
| base | a molecule that is found in DNA that is used to store information |
| chromosome | a rod-shaped structure that contains DNA and is found in the nucleus of a cell |
| gene | the information about a trait that a parent passes to its offspring |
| genetics | the study of heredity |
| heredity | the passing of traits from parents to offspring |
| meiosis | the process that results in sex cells |
| mitosis | the process that results in two cells identical to the parent cell |
| mutation | a change in a gene (can be harmful to organisms) |
| replicate | to copy itself (DNA) |
| genotype | a group or class of organisms having the same genetic information |
| phenotype | physical appearance |
| Punnett square | diagram used to predict the probability of an organism inheriting a given trait |
| dominate | stronger gene |
| recessive | weaker gene |
| alleles | when a pair of chromosomes separate during meiosis |
| Mendel | the father of genetics |
| hybrid | different genetic information |
| purebred | always produces the same traits generation after generation |
| homozygous | two alleles that are the same-TT, tt |
| heterozygous | two different alleles, Tt |
