In familial hypercholesterolemia, individuals homozygous for the allele causing the disorder completely lack receptors on liver
cells that take up cholesterol from the blood stream. Heterozygotes have one-half the number of receptors while individuals homozygous for the normal allele are phenotypically normal. This is the example of what?A. Complete dominance.B. Co-dominance.C. Incomplete dominance.D. Epistasis.
This happens when two paired alleles do not match because one could not express on the paired allele. What happens is that there will be a third phenotype that will occur.
