The Hardy-Weinberg Equilibrium
&
Sickle Cell Anemia!

Return to Mr. Lazaroff’s Biology II & II Honors

In different parts of Africa the frequency
of Sickle Cell Anemia in the population
is one of the following:

Area 1

.0025

0.25 %

Area 2

.01

1 %

Area 3

.04

4 %

    Using the Hardy Weinberg Formula,
determine what percentage (%) of the
population in each of the areas above are
CARRIERS for the trait, and therefore
RESISTANT TO MALARIA!

Interactive Hardy-Weinberg Calculator!
