Heteroduplex formed by different DNA strands from homologous sites. Additional band originating from different alleles of the Cat-In 2 locus, linked to the Ry sto gene in Solanum stoloniferum Schltdl. The heteroduplex is the first band in the upper row. The artifact was investigated with single-strand conformation polymorphism (SSCP) analysis (not shown), where this band was not detected due to it being composed of two different strands from the lower two fragments.
