| Term | Definition |
|---|---|
| Genetics | Study of how traits are inherited |
| Chromosome | Structures in a cell's nucleus that are made of DNA (genetic material) |
| Trait | A distinguishing characteristic or quality; eye color, face shape |
| Heredity | The passing of traits from parents to offspring |
| Asexual Reproduction | A type of reproduction (regeneration, budding, binary fission, vegetative propagation) in which a new organism is produced by 1 parent with identical DNA to the parent |
| Budding | A type of asexual reproduction that produces a bud that breaks away from the organism to live on its own |
| Regeneration | A type of asexual reproduction, uses cell division to re-grow body parts |
| Binary Fission | An organism splitting, making two identical organisms |
| Vegetative Propagation | The ability of plants to reproduce by producing new plants from existing vegetative structures |
| Offspring | Children or young of a particular parent, descendent |
| Sexual Reproduction | A type of reproduction in which 2 parents form a unique offspring |
| Homozygous | 2 alleles in a gene pair are the SAME for a particular trait |
| Heterozygous | 2 alleles in a gene pair are the different for a particular trait |
| Recessive | Describes a trait that is often covered up, is only seen when both alleles in a gene pair are recessive |
| Dominant | Describes a trait that is always seen anytime it is present in a gene pair |
| Hybrid | Another name of heterozygous, alleles for a trait are different |
| Purebred | Another name for homozygous, alleles for a trait are the same |
| Genotype | An organisms genetic makeup, or alleles for a trait |
| Phenotype | Physical appearance and behavior or an organism because of the genes it has |
| Punnett Square | A tool used to predict probability of certain traits in offspring |
