This is an organ that served a purpose in the distant ancestor of an organism, but is not longer pertinent in the presently existing, recently evolved, organisms.
They are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations
Natural selection, mutation, genetic drift and gene flow are all capable of causing varying changes in allele frequencies in a population. and these changes leads to the violation of Hardy-Weinberg assumptions
Hardy-Weinberg assumption states that; for a population to experience an unchanged allele frequencies, certain conditions must be met by the population such as ; absence of natural, random mating , absence of migration and absence of mutation.
Hence we can conclude that Natural selection , mutation, genetic drift and gene flow are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations

What is the question? Que necesitas?
As the wolves with short hair decreases (because the environment does not encourage their survival), there will be less competition for the food that both would need. The long haired wolf even with a recessive gene, would increase in number.
A might be true but the hair length by itself will not cause the extinction of the entire wolf population.
C is simply not true. Your givens tell you that the long hair are more likely to survive.
B is the answer, for the reason given above.
