The correct answer is :
Some substances but not other can cross the (blank ) membrane of a cell. The blank is to be filled with either cell or plasma. Cell membrane or plasma membrane is the living boundary of a cell which is made of phospholipid. It is a semi-permeable or differentially permeable membrane. It only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it

Codominance or incomplete dominance is the answer in this question. This pattern of color expression is most likely to be an example of incomplete dominance or codominance. Codominance is defined as a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed. Incomplete dominance on the other hand is a form of intermediate inheritance in which one of the allele for a specific trait is incompletely expressed over its paired allele.
