Final answer:
Albinism is a genetic disorder characterized by the lack of melanin, which is true. It affects skin, hair, and eyes pigmentation and increases sensitivity to UV light and can lead to vision problems.
Step-by-step explanation:
The statement that albinism is a genetic disorder with a lack of melanin is TRUE. Albinism affects the pigmentation of skin, hair, and eyes due to melanocytes' inability to produce melanin. This condition not only affects appearance by causing very pale skin and hair but also increases sensitivity to UV radiation and light, leading to vision problems. While albinism does not directly impact lifespan, it necessitates certain protective measures such as limited exposure to UV light to prevent sunburns and skin cancer.
