The chart shows SSR marker weights on a linear scale where each allele or 'gel band' is represented by a circle. The circle's diameter can be sized proportionally by its rareness (default: the wider the rarer) within a set of accessions. The purpose is to facilitate the visual screening and comparison of genotypes with regard to these two questions:

What is the overall pattern of alleles in a genotype?

Which genotypes have rare alleles?
