Random fertilization allows random combination of genetic information, which helps synthesize genetically unique gametes. The fusion of a unique sperm together with a unique egg can introduce further variation.

Answer:
The correct answer is - 75% or 3/4.
Explanation:
In the given question, there is a cross between III-6 and III-7 that produced two double eyes monsters and expected one more. As given in the image that the A or single eye is dominant over the a or double eye then both parents must be heterozygous as they produced double eye offspring (aa) and they do have only one eye.
then chances of single eye offspring would be -
cross: Aa and Aa
gametes: A, a and A, a
Punnett square:
             A      a
A         AA     Aa
a         Aa      aa
so there are 75% chances to have a single eye and 25% chances for a double eye.
 
        
             
        
        
        
The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and  Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.  
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
•	Phospholipids – Form a bilayer  
•	Cholesterol –improves stability and reduce fluidity
•	Proteins –integral (transmembrane) or peripheral  
•	Sugars-usually attached to proteins.
