I've run into a question that I disagree with others on but I would like to receive the input of others. The question is:
If a population is at Hardy-Weinberg equilibrium, which of the following can be predicted for the recessive alleles in the population? 1) They will eventually disappear, 2) They will be selected against, 3) They will be maintained at the same frequency, 4) They will be expressed in the heterozygous condition, and 5) They will become dominant.
Some people said that the answer to this question was that the recessive alleles would be selected against, but I interpreted the question as having the answer that the allele frequency of the recessive alleles would not change and instead would be maintained at the same frequency.
My rationale for this was that Hardy-Weinberg equilibrium means there is random mating and basically no radical shifts in allele frequencies from outside sources, such as gene flow, natural selection, etc. I would think that the allele frequency would not change, but I may be incorrect.
Is my methodology correct?
