Mutations

Based on https://en.wikipedia.org/wiki/Mutation#External_links "In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements." The organisms I choose is a snake. The snake has a gene that affect the head of the snake, the mutation cause the snake to has two head in one body. The change of this organism will affect other organism by lacking usual food source,population,etc. I think this change is agianst becuase mutation is the change of the gene and is mostly deleterious.
