When allele frequencies change because of genetic drift, you expect . A. the average fitness of the population to increase B. the average fitness of the population to decrease C. the average fitness of the population to remain the same D. The effect of drift on average fitness is not predictable

D- The effect of drift on average fitness is not predictable

Explanation:

Genetic drift is a mechanism causing change in allele frequencies in a population from one generation to another. Genetic drift happens by random sampling and the benefit or harm of the allele is not a factor in deciding which allele stays and which is deviated from.  

A beneficial allele may be lost, and a harmful allele fixed into the next generation.  Genetic drift affects both small and large populations but its effect is more pronounced in small populations.

Since Genetic drift happens by chance and any allele can be selected, the effect of the drift on the fitness of the population cannot be predicted. If a harmful allele is selected, there will be a negative effect on the fitness. On the other hand, if a beneficial allele is selected, there will be a positive effect on the fitness of the population

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
