| Heredity | the passing of traits from parent to offspring |
| Alleles | the different forms of a trait that a gene may have |
| Genetics | the study of how traits are inherited through the interaction of alleles |
| Hybrids | an offspring that was given different genetic information for a trait from each parent |
| Dominant | a trait that covers over another form of that trait |
| Recessive | a trait that is covered over by another form of that trait and seems to disappear |
| Punnett Square | a tool to predict the probability of certain traits in offspring that shows the different ways alleles combine |
| Genotype | the genetic makeup of an organism |
| Phenotype | outward physical appearance and behavior of an organism |
| Homozygous | an organism with two alleles that are the same for a trait |
| Heterozygous | an organism with two different alleles for a trait |
| Incomplete Dominance | the offspring of two homozygous parents show an intermediate phenotype |
| Polygenic inheritance | group of gene pairs act together to produce a trait |
| sex-linked gene | an allele inherited on a sex chromosome |
| genetic engineering | biological and chemical methods to change the arrangement of a gene's DNA |
