Biology Graphs: Natural Selection
There are three types of natural selection. Each type of
has very different consequences for the resulting populations. Directional
causes a shift in the
toward the left or right on the graph. Stabilizing
reduces the extremes in the population. Diversifying
ultimately encourages the
of the intermediate numbers.
Which of the three selection types would result in black or white snuzzles (represented with "S") but no gray ones?
Which of the three selection types would result in medium colored snuzzle being the most frequent in the
or dark snuzzles?
Which selection type might ultimately lead to two separate
unable to mate?
