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

Molecular models of two different substances are shown below. in the molecule on the left, the oxygen atom pulls on electrons more strongly than the hydrogen atoms. in the molecule on the right, the two oxygen atoms pull on the shared electrons with the same strength. water molecule, h,o oxygen molecule, oz when the two substances are put in the same container, they do not attract each other. why does this happen? a. they both contain oxygen. b. one is polar and one is nonpolar. c . they are both polar. d. they contain different elements.
