A biologist was studying two indigenous groups of people from different areas of the world. The first population was from equatorial Africa. The second population was from northern Europe.
The biologist was studying a gene that affects skin color. The biologist examined the gene in 100
people from each population. She kept track of how many different forms (or alleles) of the gene
she found in each population. The results are in the graph in Figure 1.
