| phenotype | outward physical appearance and behavior of an organism as a result of its genotype |
| heredity | the passing of traits from parent to offspring |
| genetics | the study of how traits are inherited through the action of alleles |
| homozygous | describes an organism with two alleles that are the same for a trait |
| genotype | the genetic makeup of an organism |
| hybrid | an alternate form that a gene may have or a single trait; can be dominant or recessive |
| punnett squares | a tool to predict the probability of certain traits in offspring that shows the different ways alleles can combine |
| dominant | describes a trait that covers over, or dominates, another form of that trait |
