Supplementary Material 2. Figure S2: Distribution of expressed genes and DEGs from each clusters of embryos transcriptomic analysis. Clusters 1, 2, 3, 4 respectively contains 2742, 3698, 1215, 591 DEGs. The aggregate clusters 5 and 6 contains 1651 DEGs. Distribution of expressed genes (gold) and DEGs from each cluster or aggregate clusters (black) on the three autosomes (A1, A2, A3) and on X chromosome was performed using R project. The y axis represent the number of expressed genes or DEGs by sliding window of 1 Mb (x axis). Two region of aggregate cluster 5 and 6 were significantly DEGs enriched (Student’s T test: t = 9.9344, df = 27.388, p-value = 1.406e-10). These two enriched regions (mean 17.4 DEGs by Mb) represent 50 Mb in end of X and 10 Mb in beginning of A2. Regions not enriched in DEGs contain on average 1.5 DEGs by Mb.
