Reciprocal vs. initial cross, highlighting 'consensus' imbalanced isoforms and X transcripts. Scatterplot of log fold changes between haplo-isoforms in the reciprocal (F1r) and the initial (F1i) cross, highlighting X transcripts in blue, isoforms termed 'consensus' maternally imprinted in red and 'consensus' paternally imprinted in green. 'Consensus' imprinted genes were chosen by  as those with more than two heterozygotes exhibiting imbalance in favor of the same parental sex, at least one of which was significant in a χ2 goodness-of-fit test with a P-value threshold of 0.05.
