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,
or
genetic drift.

The right option is; gene mutation

The most likely the cause of this difference from the rest of the population is gene mutation.

Gene mutation is a perpetual change in the DNA sequence that forms a gene, in which the sequence is different from what is present in most people. Mutations can influence anywhere from a large part of a chromosome to a single DNA molecule. Gene mutations can be grouped into two major ways which are; (i) hereditary mutations; inherited from a parent, and (ii) acquired (or somatic) mutations; caused due to errors during DNA replication ,or by environmental factors such as ultraviolet radiation from the sun.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
