Co-dominance is when both the alleles of a gene in a heterozygote show. In the case of sickle cell anemia (since it is a co-dominant trait) even if the person only has one sickle cell allele, symptoms of sickle cell will still show up in that person. That's why the person in this example has both misshapen and healthy red blood cells.
Hypertonic is where the solution has a lower water potential than the other side of the membrane. It has less water molecules and osmosis may occur under that in the presence of semi permeable membrane. Where water will flow from a higher water potential to lower water potential region
