Figure 4

The level of polymorphisms for the Yb8a1, Yb10 and Yb11 subfamilies. The blue columns at the front indicate the number of polymorphic insertions observed in the population and the orange columns in the middle represent the number of insertions observed in other populations but not in the population. The presence or absence of polymorphic insertions in Chinese and Japanese populations could not be determined and these are labeled as 'unascertained’ and represented by grey bars. CEU, Utah residents with European ancestry; CHB, Han Chinese from Beijing areas; JPT, Japanese from the Tokyo area; YRI, Yoruban.
