| Tetrad | a structure that forms 4 chromatids during meiosis |
| Trait | specific characteristic such as color, height, color of eyes, hair |
| Hybrid | offspring of crosses between parents with different traits |
| Probability | likelihood that a particular event will occur |
| Independent Assortment | genes for different traits can segregate indedpendently during the formation of gamets |
| Sex Linked | gene on a sex chromosone |
| Pedigree | chart that shows the presence or absence of a trait according to the relationships within a family across several generations |
| Crossing Over | process in which homologous chromosones exchange portions of their chromatids during meiosis. Produces new combination of alleles in cells. |
