Answer:
Total 495 liters of natural oil are needed.
Explanation:
It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil. 
It means the ratio of natural oil and synthetic oil is
 
 
Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.
It means the ratio of natural oil and synthetic oil is
 
 
Equate both ratios,

On cross multiplication we get


Divide both sides by 8.


Therefore total 495 liters of natural oil are needed.
 
        
             
        
        
        
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.
