|---|---|
| DNA | deoxyribonucleic acid, the material that contains the information that determines inherited characteristics |
| Chromosomes | in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA |
| cell cycle | the life cycle of a cell |
| interphase | |
| mitosis | |
| cytokinesis | the division of the cytoplasm of a cell; cytokinesis follows the division of the cell’s nucleus by mitosis or meiosis |
| Homologous Chromozones | |
| meiosis | |
| asexual reproduction | reproduction that does not involve the union of sex cells and in which one parent produces offspring that are genetically identical to the parent |

| fertilization | the union of a male and female gamete to form a zygote |
| heredity | |
| gene | one set of instructions for an inherited trait |
| allele | one of the alternative forms of a gene that a characteristic, such as hair color |
| genotype | |
| phenotype | |
| dominant | describes the allele that is fully expressed when carried by only one of a pair of homologous chromosomes |
| recessive | |

| artificial selection | one of the alternative forms of a gene that a characteristic, such as hair color |
| genetic engineering | a technology in which the genome of a living cell is modified for medical or industrial use |
| clone | an organism, cell, or piece of genetic material that is genetically identical to one from which it was derived |
