Evo-Ed: Integrative Cases in Evolution Education

Cases for Evolution Education

The Selective Farmer

In this game you will be given a choice of whether you want to select for round peas, wrinkled peas, or neither. After your selection, you will harvest the field of peas shown and then you will automatically replant based on your selection. For example, if you had decided to select for round peas, the simulator will only replant the round pea phenotype.
- For each of the three scenarios, how many generations does it take for one allele to become fixed in the population?
- Does this happen more quickly when selecting for the round phenotype or for the wrinkled phenotype?
- How difficult do you think it was for ancient farmers to remove the R allele from their cultivated pea populations?
