| Gametogenesis | The formation of gametes (egg and sperm). |
| Diploid numbers | The number of chromosomes found in the double set of chromosomes found in ALL body cells. |
| Haploid numbers | Half the diploid number of chromosomes found in egg and sperm of a species. |
| Gametes | Sex cells; egg and sperm. |
| Ovaries | Female gonad where eggs are matured. |
| Testes | Male gonad where sperm is created. |
| Meiosis | Process to create egg and sperm cells; the result is four cells with half the number of chromosomes from the parent cell. |
| Formation | Development of a particular thing |
| Crossing over | The exchange of chromosome pieces. |
| Disjunction | The separation of the homologous chromosome pairs during the first division of meiosis. |
| Non-disjunction | The failure of homologous chromosomes to separate. |
| Spermatogenesis | One cell becomes four sperm. |
| Oogenesis | One cell becomes one viable egg cell and three polar bodies. |
| Replicate | To double. |
