It depends on what kind of solution is referred as 0.65 M. If the solution where the red blood cell is present is hypertonic, the red blood cell will shrink. If the solution is hypotonic, the red blood cell will expand. If the solution is isotonic, the red blood cell will not expand or shrink.
The genotype depends if the purple flower is heterozygous dominant of homozygous dominant. But the total possible phenotypes available is 2, purple or red.
