| mitosis | cell division that results in the formation of identical daughter cells |
| meiosis | cell division that results in four reproductive cells |
| interphase | phase where the parent cell chromosomes doubles |
| prophase | phase where the spindle forms and the nuclear membrane disappears |
| metaphase | phase where pairs of chromosomes line up on the spindle attached by their centromeres |
| anaphase | phase where the spindle pulls pairs of chromosomes to opposite ends of the cell |
| telophase | phase where the nuclear membrane forms around chromosomes at opposite ends of the cell |
| cytokinesis | phase where the parent membrane pinches in and the cytoplasm divides |
| dominant trait | trait that is expressed when two different genes for a trait are present |
| recessive trait | trait that seems to disappear when two different genes for the same trait are present |
| genes | units of heredity |
| genetic engineering | process in which genes, or pieces of DNA, from one organism are transferred into another organism |
| genetics | the study of heredity, or the passing on of traits from an organism to its offspring |
| genotype | genetic makeup of an organism |
