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.
I hope it helps, Regards.
