SNPs are one form of mutation. A mutation does not need to be limited to a single nucleaotide and so entire genes could be deleted, repeated, replaced… But since SNPs are only one base pair, they are more survivable as the random effect of a mutation is more likely to be deleterious to the organism.
Since SNPs are more survivable, they can accumulate in an individual and provide valuable insight on inheritance, relatedness to other individuals and evolutionary history.
Thanks!
Aren't Snp's just another name for Mutations?
