In a population of seals, most of the seals have similar coloring. However, one seal has albinism. This seal is white and is almost completely blind. What is most likely the cause of this difference from the rest of the population? gene flow natural selection gene mutation genetic drift

The cause of albinism in one seal in a population of seals with similar coloring is gene mutation. Albinism is a recessive trait caused by a mutation in the gene for the enzyme which is important in melanin synthesis. Since melanin is a pigment responsible for hair and skin colour, the gene mutation will cause the absence of melanin and thus, albinism.
