Heterozygous sequences of the hybrid, H. kuda × H. reidi, in ribosomal protein S7 gene. Double peaks of single nucleotide polymorphism (SNP, e.g., A and B) and insert/deletion (indel, C) are suggested by the site number and red nucleotide. Indel overlapping of the aligned sequences represents the double peak chromatogram at a single base pair site (arrow)
