75. An isolated population of humans with approximately equal numbers of blue-eyed and brown-eyed individuals was decimated by an earthquake. Only a few browneyed people remained to form the next generation. This kind of change in the gene pool is called a
(a) Hardy-Weinberg equilibrium
(b) blocked gene flow
(c) genetic drift
(d) gene migration.
