This type of natural selection is referred to as directional selection. In this type of natural selection, either one phenotype is preferred or the other; therefore, there is no equilibrium between the populations of the phenotypes that are present.
Examples of organisms that have undergone directional selection are black bears during the ice ages, African chichlid and sockey salmon.

Now, let us analyse the data given in question number 2 .

No. of grizzly bear deaths in Alberta from 1976 to 1988 = 581

No. of grizzly bear deaths in Alberta from 1988 to 2000 = 281

From the above data we can clearly say now that the grizzly bear population deaths starts increasing from 1990.

So, the prediction made in question no. 1 that " the government of Alberta introduced the hunting lottery award in 1990 because in 1989 it decreases and then it starts to go up again in 1990",
