1. Analyze Data What is the relationship between the places where malaria is common and where
the sickle cell allele is commonly found?
2. Construct an Explanation In 1805, a Scottish

Africans phenotype helped them survive
3. the As the map shows, the
sickle cell allele pot found in African popula.
tions that are native to southern Africa. Form a
hypothesis to account for this discrepancy
Sickle cell allele
