| Term | Definition |
|---|---|
| DNA | Chemical in living things that contains coded instructions that store and pass on genetic information |
| Double Helix | The structure of DNA because it looks like a twisted ladder or spiral staircase |
| chromosomes | strands of tightly wound DNA |
| Genes | sections of a chromosome that carry the code for a particular trait |
| Mendelian genetics | explains how traits are passed on through generations |
| allele | form of a gene for a particular trait |
| dominant allele | form of the trait that masks or hides the other form |
| recessive allele | form of a trait that is masked or covered up when the dominant form of the trait is present |
| genotype | the genetic makeup of an organism |
| phenotype | the physical trait that shows up as a result of the genotype |
| punnett square | a tool used to predict genotype and phenotype of offspring |
| genetic engineering | manipulation of the genetic code for medicine, agriculture etc. |
| inherited | traits expressed in genes |
| acquired | skills acquired through practice and injuries occurring from the environment |
| sugars, nitrogenous bases, and phosphates | traits expressed in genes |
| Gregor Mendel | often considered the "father of genetics" for his study of the inheritance of traits in pea plants |
| Rosalind Franklin | Discovered that DNA is a strand of molecules in spiral form |
| Watson and Crick | came up with the Double helix model of DNA |
| genetics | the scientific study of heredity |
