A fur color gene in rabbits has a white dominant (W) and brown recessive allele (w).  The environment changes suddenly and none of the white rabbits survive.  In a population of 10,000 rabbits the initial frequency of W in the pool was 0.7.  How many generations would be required to eliminate all W alleles from the population? Assume that there is no mutation and the population meets all other Hardy-Weinberg conditions.

A. 1
B. 5
C. 2
D. 20
