Genetics & DNA
| Question | Answer |
|---|---|
| Genetics | The study of heredity |
| Trait | Characteristic |
| Inherited Trait | Trait that is passed from parents to offspring & inherited traits are controlled by genes |
| Heredity | Passing of traits from parents to offspring |
| Chromosome | Cell parts that determine what traits a living thing will have . organisms receive chromosomes from their parents |
| DNA | Deoxyribonucleic acid . large molecule contained in chromosomes |
| Genes | Parts of a chromosome that control inherited traits |
| Dominant Gene | Gene whose trait always shows itself |
| Recessive Gene | Gene of a trait that is hidden when the dominant gene is present |
| gene of a trait that is hidden when the dominant gene is present | Having two like genes for the same trait |
| Heterozygous | Having two unlike genes for the same trait |
| Punnett Square | A chart that shows possible gene combinations |
| Incomplete Dominance | The alleles of both parents are blended |
| Codominance | Both alleles of a gene are shown |
| Gene Splicing | Moving a DNA section from genes of one organism to genes of another organism |
| Inbreeding | Mating closely related organisms |
| Genetic Engineering | Methods used by scientists to produce new forms of DNA |
| Hybridization | Crossing two different kinds of organisms |
| Controlled Breeding | Crossing organisms to produce offspring with desirable traits |
| Mutation | A change in a gene |
| Gamete | A reproductive cell |
