| Term | Definition |
|---|---|
| hybrid | An organism that has two different alleles for a trait. |
| dominant | An allele whose trait always shows up in the organism when it is present. |
| gene | The set of information that controls a trait; code in the DNA. |
| alleles | The different forms of a gene. |
| heredity | The passing of traits from parents to offspring. |
| purebred | The offspring of many generations that have the same traits. |
| trait | A characteristic that an organism can pass to offspring through genes. |
| genetics | The scientific study of heredity. |
| probability | A number that describes how likely it is that an event will occur. |
| phenotype | An organism's physical appearance or visible traits. |
| recessive | An allele that is masked when a dominant allele is present. |
| codominance | A condition in which the two alleles of a gene are neither dominant nor recessive. "red + white = pink" |
| heterozygous | Having two different alleles for a trait. "Tt" |
| genotype | An organism's genetic makeup or allele combinations. |
| Punnett Square | A chart that shows the possible combinations of alleles that result from a genetic cross. |
| homozygous | Having two identical alleles for a trait. "TT, tt" |
| Incomplete Dominance | Both traits are shown. "one brown eye and one blue eye" |
| chromosome | located in the nucleus of a cell, stores the genetic information that control your traits |
