| Allele | Different versions of a gene. |
| Heredity | The passing of traits from parent to offspring. |
| Offspring | Babies. |
| Genetics | The study of how traits are inherited. |
| Gregor Mendel | The Father of Genetics |
| Purebred | Homozygous alleles |

| Punnett square | Tool used to predict offspring genotypes. |
| Genotype | What alleles are present. |
| Phenotype | The physical appearance. |
| Probability | Predicting the chance something will happen. |
| Gene | A specific location on a chromosome that controls a trait. |
| Incomplete Dominance | When two alleles do not mask each other. |
| Sex-linked gene | Gene located on the X and Y chromosomes. |
| Polygenic Inheritance | When more than one gene controls a trait. |

| Genetic Engineering | Changing the DNA sequence of a gene. |
| Acquired | A trait that is not part of the genetic makeup of an organism. EX. curly hair from a perm |
| Inherited trait | A trait that is controled by the genes. It is passed on from one generation to the next. |
