Hardy-Weinberg Equilibrium Gizmo
Assessment
The screenshot below shows a possible initial condition of the Gizmo. Which of the
following statements is most accurate? Correct answer- B. After the simulation has run
for 5 generations, the proportion of D alleles will still be approximately 75%.
A group of parrots is 20% DD, 40% Dd, and 40% dd. What is the allele percentage of d
in this group? Correct answer- C. 60 percent
If 50 DD/dd pairs of parrots mate, and each pair has 2 offspring, how many of the 100
offspring would you expect to be Dd? Correct answer- B. 100
Which of the following groups of parrots is most likely in Hardy-Weinberg equilibrium?
Correct answer- C. A group with 25 DD parrots, 50 Dd parrots, and 25 dd parrots.
A biologist conducts an experiment by releasing 50 Dd parrots on a remote tropical
island, Alpha. On another remote island, called Beta, she releases 25 DD parrots and
25 dd parrots. What is the most likely description of the parrot populations after several
generations? Assume random mating and equal chances of survival for all genotypes.
Correct answer- B. The genotype percentages on each island will be approximately
25% DD, 50% Dd, and 25% dd.
