Question

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

Answer 1

Gene mutation.

Albinism results from a mutation in genes controlling melanin production (e.g., tyrosinase), which also affects eye development and causes poor vision.
