Achromatopsia, a form of colorblindness, affects an estimated 1 in 30,000 people worldwide. Pingelap is an island and part of the Federated States of Micronesia. In the late 18th century a typhoon hit and the human population on the island went from 500 people to about 20 people. The survivors reproduced and by the 1900s the population was back to about 600 people. However, the incidence for achromatopsia in the Pingelap population is now about 1 in 1,800 people. Which process of evolution has most likely occurred?

The two sets of pie charts above show two possible results from a study like the Rosenberg study that we examined in class. Both possibilities show possible results for the same locus. Colors show different alleles. For each statement, select whether possibility 1, possibility 2, neither possibility, or both possibilities support the statement. Options may be used more than once. Prediction 1) There is more variation within geographic regions than between geographic regions. [blank1] Prediction 2) There is more variation between geographic regions than within geographic regions. [blank2] Prediction 3) It is possible to identify someone’s geographic origin based on their allele at this locus. [blank3] Prediction 4) It is impossible to identify someone’s geographic origin based on their allele at this locus. [blank4]
