^aUpper values in each cell are the number of elements per megabase of DNA in each category, and values in parentheses are the fraction of DNA in each location occupied by TEs. Significance levels are shown for comparisons between the regions of reduced recombination compared with the chromosome arms by the Mann-Whitney U test

^bClass I and Class II elements are shown excluding gypsy and CACTA-like elements, respectively. Two-tailed significance

^*, P <0.05; ^**, P <0.01
