L1Hs insertions found in various human genomes. L1Hs insertions found for each individual are categorized based on whether or not they are in the reference genome. Reference insertions are subcategorized into pre-Ta, Ta-0, and Ta-1 based on the presence of diagnostic nucleotides. Uncategorized Ta elements (green) are missing one or both characters necessary for placement into either group, often because the nucleotides are not present due to 3′ truncation of the elements. Bars marked with an asterisk (*) indicate samples that did not yield the expected number of insertions, likely due to poor genomic DNA quality or errors in sample preparation.
