Figure 6 From:Epigenetic history of an Arabidopsis trans-silencer locus and a test for relay of trans-silencing activity Test for relay of trans-silencing ability from C73 via L91' to E82.For details see text and Tables. Under 'Expected' the figure shows the predicted results under the null-hypothesis that L91' wouldnottrans-silence E82. This is referred to as an additive interaction. Back to article page
