There are three different types of natural selection and all three types affect the frequency of alleles in a population. By analyzing the
graphs above, determine which type of natural selection is matched correctly to the effect it has on allele frequencies in populations
for certain traits.
All are matched correctly.
Stabilizing Selection; Infant mortality increases if their weight is
significantly more or less than 7.5 lbs.
Directional Selection; A very effective insecticide, DDT, lost it effectiveness
on insects after years of extensive use.
Disruptive Selection; Peppered moths in London were darker near
industrial areas and lighter in color in the more rural areas.
