Final answer:
Albinism is a genetic disorder characterized by the absence of pigment in the skin, hair, and eyes due to the inability of melanocytes to produce melanin.
Step-by-step explanation:
The absence of pigment in the skin, hair, and eyes is called albinism. Albinism is a genetic disorder that results from the inability of melanocytes to produce the pigment melanin. Individuals with albinism usually have very pale skin, white or pale hair, and light eye color due to the lack of melanin, which provides color and some protection against the sun's UV radiation. Such individuals often need extra protection against sunlight to prevent sunburn and skin cancer and may experience vision problems. Albinism is inherited and can occur in both humans and animals. It's important to differentiate albinism from other conditions like vitiligo, which causes the loss of skin color in patches, or tyrosinosis and alkaptonuria, which are different genetic disorders.
