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.
They are called the building blocks of an organism because all living things are made up of billions of cells that can reproduce, build and change that's why it is called the building blocks of all living things.
