WebVery often this definition also comprises single-base insertions and deletions (so called “indels”). SNPs are the most abundant polymorphisms in the human genome, accounting for more than 90% of all sequence variations. In diploid species, SNPs are usually biallelic polymorphisms but have the potential to be tri- or even tetra-allelic. If ... WebApr 11, 2024 · Definition. 00:00. 00:46. An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.
