Final answer:
Vitiligo is a condition where melanocytes in certain areas lose their ability to produce melanin, leading to depigmented patches on the skin. Albinism, on the other hand, is a genetic disorder that affects the production of melanin, resulting in individuals with albinism appearing white.
Step-by-step explanation:
In vitiligo, the melanocytes in certain areas lose their ability to produce melanin, possibly due to an autoimmune reaction. This leads to a loss of color in patches on the skin. While albinism is a genetic disorder that affects the ability of melanocytes to produce melanin, resulting in individuals with albinism appearing white or very pale.
