| Generation | a group of individuals born and living at about the same time |
| Variation | any difference in traits between individual organisms |
| Distribution | the number of individuals with each trait in a population |

| Prediction | a group of the same type of organism living in the same area |
| Cause | an event or process that leads to a result or change |
| Effect | a result or change that happens because of an event or process |
| Gene | an instruction for making a protein molecule |
