Question

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?

Answer 1

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.

Step-by-step explanation:

cause it is

Answer 2

Answer is from dd parents in this simulation it very lucky to survive as a long as they did.
