Besure to include the following keywords in your explanation: selection, fitness, survival. 7. Why could milk have provided strong favorable selection for lactase persistence?8. In humans, the AMY1 gene produces the enzyme amylase in cells of the salivaryglands. Amylase breaks down starch (a polysaccharide) into the sugar maltose (adisaccharide). People from cultures with diets high in starch produce more amylasethan people from cultures with diets low in starch because of a mutation in the AMY1gene. Explain in two to three sentences why the frequency of this AMY1 mutationwould have increased in frequency in populations with a high starch diet.

9. Study the figure below. Each pie chart represents a distinct population. The degree
to which the pie chart is filled in illustrates the percentage of individuals in that
population who are lactase persistent.
Lactase persistence
Lactase non-persistence O
a. Identify two trends you see in the data. Provide evidence to support each trend.
b. State one possible hypothesis that can explain the global distribution of lactase
persistence (lactose tolerance) and lactase nonpersistence (lactose intolerance). Be
sure to include the following keywords in your explanation: selection, fitness, survival.

7. Why could milk have provided strong favorable selection for lactase persistence?
8. In humans, the AMY1 gene produces the enzyme amylase in cells of the salivary
