Note about the question:
Probably there are options for this question, but I failed in finding them. However, in the explanation box I will explain the reason for the lack of white flowers in the F1. 
Answer:
The purple phenotype is dominant over the white phenotype. The allele that expresses the purple color is dominant and, in a heterozygous state, hides the expression of the recessive allele that expresses the white color. Principle of dominance. 
Explanation: 
Due to technical problems, you will find the complete explanation in the attached files.
 
        
             
        
        
        
The correct answer is - Most killer whales congregate in the areas that are near the Arctic/Antarctic Circles.
The killer whales have a very large distribution, and they can be found in all oceans, apart from the Southern Ocean. It is noted though that the population density of the killer whales differs from place to place. The higher concentrations are found around the Arctic and Antarctic Circles, where there's cool rich waters, while in the lower latitudes they are much rarer. The reason for this probably lies in the fact that most of the animals that are considered to be the prime food source of the killer whales are living in this rich cold waters.
