Hardy-Weinberg Equilibrium Gizmo Assessment

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?

B. 100

The screenshot below shows a possible initial condition of the Gizmo. Which of the following statements is most accurate?

B. After the simulation has run for 5 generations, the proportion of D alleles will still be approximately 75%.

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.

B. The genotype percentages on each island will be approximately 25% DD, 50% Dd, and 25% dd.

A group of parrots is 20% DD, 40% Dd, and 40% dd. What is the allele percentage of d in this group?

C. 60 percent

Which of the following groups of parrots is most likely in Hardy-Weinberg equilibrium?

C. A group with 25 DD parrots, 50 Dd parrots, and 25 dd parrots.
