A-tail length variation within the population. (A) Histograms of the A-tail length distribution of the selected Ya5a2 element from the same locus of different individuals. The histogram reflects the A-tail length (X-axis) and the amount of elements for that length (Y-axis). The allele frequency for each locus is indicated as fixed present (FP), intermediate (IF), or high frequency (HF); see definitions in Table 3. (B) Histogram of the distribution of the Ya5 elements retrieved form the genome draft sequence (white bars) and the combined data of all the individual Ya5a2 elements (black bars) from different populations analyzed, as listed earlier.
