| Cell cycle | the series of events in which a cell grows, prepares for division, and divides to form two daughter cells |
| Function | the work that DNA tells the genes to do |
| Pedigree | a tool that geneticists use to map out the inheritance of traits |
| Meiosis | the process that occurs in the formation of sex cells (sperm and egg) by which the number of chromosomes is reduced by half |
| Chromatids | the structure formed when a chromosome divides during meiosis |
| Mitosis | the second stage of the cell cycle during which the cell's nucleus divides into two new nucleus and one set of DNA is distributed into each daughter cell |
