The graph below shows genotype percentages for generations 20 through 26. The initial genotype percentages were 34% DD, 32% Dd, and 34% dd. The fitness levels were 100% for DD and Dd; and 60% for dd. Why does the deleterious dd genotype persist for so long in the simulation?

The
graph below shows genotype percentages for generations 20 through 26.
The initial genotype percentages were 34% DD, 32% Dd, and 34% dd. The
fitness levels were 100% for DD and Dd; and 60% for dd. The reason
why the deleterious dd genotype persists for so long in the
simulation is…





Answer:
C) Although dd parrots are much less likely to survive and reproduce,
new dd parrots are constantly being born from Dd Dd pairs.
