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
explorer named Mungo Park led an expedition
of European geographers to find the source of
the Niger River in Africa. The journey began with
a party of 45 Europeans. During the expedition,
most of these men perished from malaria. Their
native guides and the other natives they encoun-
tered were seemingly unaffected Use the data
to construct an explanation for why the native
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
Answer the three questions, please.
