If the offspring show only half the intensity of black pigment after one generation, this means that the black pigment is blending with the white pigment. In the next generation, the offspring will have 1/4 the intensity of black pigment (half of half), in the next generation, 1/8 (half of 1/4), and in the fourth generation, 1/16th (half of 1/8). Therefore, four generations would be required for the offspring to show 1/16th the intensity of black pigment.
