Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.

Answer:
c. Would have deviated from the 9:3:3:1 phenotypic ratio
Explanation:
<em>If two genes are linked together on the same chromosome, the phenotype of the F2 generation would have deviated from 9:3:3:1.</em>
Two genes whose loci are close on the same chromosome are said to be linked. Linked genes have higher frequency of recombination than genes that are not linked.
<u>Hence, while genes that are not linked assort independently to produce 9:3:3:1 phenotypic ratio at F2, linked genes do not assort independently and the higher frequency of recombination ensures that they standard phenotypic ratio is deviated from.</u>
The correct option is c.
I believe the answer is B,( Allowing specific substances to flow into the cell).
Membrane protein is found in all types of cell membrane, it can either be integral protein, which is embedded within the membrane or associated protein, which is associated with the surface of cell membrane of phospholipid bilayer.
It performs several functions such as cell to cell communication, molecular transport and cell signaling.
Embedded proteins are proteins which are found in the cell membrane, which are completely embedded in the bilayer membrane of the cell membrane. It consists of hydrophilic head and hydrophobic tail. The head face towards the water molecule and tail face inward away from the water molecule. These protein help in the movement of molecules in and out of the membrane.
Example of embedded proteins: Channel proteins and carrier proteins and are example of some of the embedded proteins.
