WebSingle nucleotide polymorphisms (SNPs) are polymorphisms that are caused by point mutations that give rise to different alleles containing alternative bases at a given position of nucleotide within a locus. Due to their high abundance in the genome, SNPs already serve as the predominant marker type.
WebInsertion–deletion mutations (indels) refer to insertion and/or deletion of nucleotides into genomic DNA and include events less than 1 kb in length.
