TABLE 3

Distribution of expression states among the mix, F1, synthetic, and Maxxa and their biological interpretation

Genotype comparisonGene × tissue combinations showing pattern (% of total)Biological description
Mix = F1 = synthetic = Maxxa with equal A–D expression6 (6.4)No change
Mix = F1 = synthetic = Maxxa with unequal A–D expression11 (11.7)Change due to A–D divergence
Mix ≠ F1 = synthetic = Maxxa23 (24.4)Change due to genome merger
Mix = F1 ≠ synthetic = Maxxa5 (5.3)Change due to polyploidy alone
Mix = F1 = synthetic ≠ Maxxa9 (9.6)Change due to polyploid evolution
Mix ≠ F1 ≠ synthetic ≠ Maxxa16 (17)Change due to all sources
Mix = F1 ≠ synthetic ≠ Maxxa6 (6.4)Change due to polyploidy and polyploid evolution

  • The first nine rows compare the distribution of expression categories for all available gene × tissue combinations among all four taxa. The next four rows compare just F1, synthetic, and Maxxa, and the last two only synthetic and Maxxa.
