*Number of repeats covered by at least four ESTs. Number of polymorphic sequences immediately upstream (up) and downstream (down) of repeats; the percentages in parentheses were calculated by taking them together. Number of repeat polymorphic variants involving gaps with respect to the total number of variants.
