Explanation / Answer

Firstly to know more about the question we must be knowing what Hardy-Weinberg population genetic says...

It states that "Allele and genotype frequencies in a population tends to remain constant in the absence of disturbing influences that are : 1) non random mating.

2) mutation

3) selection

4) limited population size

5) random genetic drift

6)Gene flow

Now according to it there must be an equilibrium that shout be maintained in frequencies of population if there are no environmental factors that are responsible for that mutation to occur.

The data given reveals us the west, central,eastern population of flower Linnanthus Parryae.

Now, looking at the picture n table give above there are stats that reveal mutation and appearance of blue flower in an area of 900 square miles in Mohave Dessert.It is doneby studying 4000 plants in area of 30 square miles. According to which we can say that the mutation is occuring least in central zone moderate in east zone and maxium in west zone. So yes, there are evidence of subdivision..n that may occur maximum in Western area may be due to climatic conditions or any other factors .. This can be seen by observing the fig.4.2 in the question ..in central area frequency is constant maximum places so it show least evidence of subdivision and similarly in west area it's showing maximum frequency of mutation so there are most chances of sub division ..And this is exactly what is revealed in table 4.1 in numerical calculations.

Also we can take it this way to that there was more area n less mutation in central area so there is least chance of subdivision.

And in this way we can support Hardy-weinberg's population genetics statement which we have talked about in the very beginning of our answer.
