8-11 is -3. When subtracting a bigger number from a smaller number, the answer will always be negative.
The answer is C. Genetic drift is the change of an allelic frequency due to random sampling in a population. When the brown and black bottles are preyed upon compared to the green bettles, their numbers in a population decrease. Therefore the next generations/offsprings of bettles population is more likely to be of green beetles since they will be more in the parent population. The allelic frequency of the allele for green bettles becomes higher than that of brown and black beetles. Eventually, after generations, the black and brown beetles may be eliminated from the population
