High polymorphic rate of young SINE subfamilies. A Insertion ages of SINEA subfamilies. The X-axis represents insertion ages (million years ago, Mya), and the Y-axis represents the genome coverage (%) of SINE subfamilies. B Predicted polymorphic ratio of SINE insertions from seven SINE subfamilies representing different insertion ages. C Representative results of the BLAST prediction and PCR verification. D The results of PCR verification for 25 predicted polymorphic and 25 non-polymorphic insertions from different SINE subfamilies (primers listed in Additional file 2)
