 Heredity | The passing of traits to offspring |
| Genetic engineering | Clue: Biological and chemical methods to change the arrangement of a gene's DNA to improve crop production, produce large volumes of medicine, and change how cells perform their normal functions. |
| Phenotype | Clue: The way an organism looks and behaves as a result of its genotype. |
| DNA | Clue: Deoxyribonucleic acid; the genetic material of all organisms. |
| Meiosis | Clue: Reproductive process that produces four haploid sex cells from one diploid cell. |
| Dominant | Clue: Describes a trait that covers over, or dominates, another form of that trait. |
| Gene | Clue: Section of DNA on a chromosome that contains instructions for making specific proteins. |
| Recessive | Clue: Describes a trait that is covered over, or dominated, by another form of that trait and seems to disappear. |
| Incomplete dominance | Clue: Production of a phenotype that is intermediate between the two homozygous parents. |
| Genotype | Clue: Genetic makeup of an organism. |
| Homozygous | An organism with two genes that are the same |
| Genetics | Clue: The study of how traits are inherited through the interactions of alleles. |
| Punnet square | Clue: A tool to predict the probability of certain traits in offspring that shows the different ways alleles can combine. |
| Sex-linked gene | Clue: An allele inherited on a sex chromosome and that can cause human genetic disorders such as color blindness and hemophilia. |
| Heterozygous | Clue: An organism that has two different alleles. |
| Allele | Clue: The different forms of a trait that makes up a gene pair. |
| Polygenetic inheritance | Clue: Occurs when a group of gene pairs act together to produce a trait. |
| Hybrid | Clue: Offspring that was given different genetic information for a trait from each parent. |
