| Heredity | Pasing of traits from parents to offspring |
| Allele | A different form a gene may have for a trait |
| Genetics | The science of how traits are inherited through alleles passed on from one generation to another |
| Dominant | A form of a trait that is the strongest |
| Genetic engineering | Changing a cells DNA sequence to produce desirable traits or eliminate undesirable ones |
| Genome | A map of the location of individual genes on every chromosome |
| Genotype | The genetic make up of an organism for a trait |
| Heterozygous | Organisms that have 2 different alleles for a trait |
| Homozygous | Organism that have 2 of the same allels for a trait |
| Incomplete dominance | Phenotype in an ofspring that is imtermediate to the 2 homozygous parents |
| Multiple alleles | Having more than 2 alleles that control a trait |
| Pedigree | A diagram or chart that shows the occurrence of a trait in the family |
| Phenotype | Physical trait that shows as a result of the genotype |
| Polygenetic Inheritance | A group of genes act together to produce a specific trait |
| Punnet Square | A tool that shows how to predict the probability of offspring |
| Recessive | The form of a trait that is hidden or weaker |
