Albinism is a genetic condition characterized by a deficiency in the production of melanin, the pigment responsible for coloring in hair, skin, and eyes. Individuals with albinism lack sufficient melanin due to mutations in genes that are involved in the melanin biosynthesis pathway. This condition results in very light skin, hair, and eye color, and it can lead to vision problems and increased sensitivity to sun exposure due to the lack of protective pigmentation.

In contrast, the other conditions listed do not affect pigment production. Polydactyly is a genetic condition resulting in extra fingers or toes. Hemophilia is a blood disorder that impairs the body’s ability to clot blood, and Tay Sachs disease is a neurodegenerative disorder caused by a deficiency of an enzyme that leads to the accumulation of harmful substances in the brain. Each of these disorders involves different biological systems and has distinct clinical manifestations, making albinism the correct choice in this context.
