QuestionChoice
The Hardy-Weinberg equilibrium refers to what a population looks like when it is not evolving, the population will stay the same over generations. As a result, there should be **no** preferential selection of genotypes and therefore no evolving for the equilibrium to be applied.

a
No preferential selection of genotypes
QuestionChoice
Smaller populations would be more susceptible to genetic drift (change in an allele frequency). Therefore, the populations should be as close to infinite in size to apply to this equilibrium.

c
Smaller populations
QuestionChoice
If new alleles are present this can be a strong agent of evolution. Therefore, to be applicable to the equilibrium there should be **no** new alleles present

d
New alleles present
QuestionChoice
Random mating is required for this equilibrium to hold true. This is because reproduction will then be the result of two random events so the probability of any offspring genotype will be the probability of the sperm and egg producing that genotype.

b
Non-random mating
QuestionChoice
If there is a preferential selection of genotypes, the more advantageous genotype will be reproduced and will survive in a given environment. If an allele becomes less advantageous its frequency will drop throughout generations. Therefore, there should be **no** preferential selection of genotypes for the equilibrium to be applied.
