| Heterozygous (HYBRID) | Two DIFFERENT alleles for a trait (Tt, Bb). Also called HYBRID |
| Homozygous (PUREBRED) | Two identical alleles for a trait (TT, tt, bb, BB). Also called PUREBRED |
| Recessive | A form of a trait that can be hidden (lower case letter b, n, f, t) |

| Breed | To produce offspring |
| Traits | A genetic characteristic (hair color, freckles, dimples) |
