Which of the above given statements is/are correct?
Answer: 1, 2, 3 & 4
Notes: Melanism is the increased production of melanin, resulting in dark skin or hair, as seen in black squirrels. Pseudomelanism, or false coloration, features dark spots or stripes that make an animal appear melanistic. Industrial melanism occurs when dark-colored individuals are favored by natural selection, exemplified by the peppered moth. Amelanism is the absence of melanin, the opposite of melanism, observed in lab mice.
