Allelic expression of XIST transcripts for five female mules in chorionic girdle, chorion, and fetus samples. (A) The horse/maternal expression of XIST transcripts in five female mule chorionic girdle samples (thick blue line). The allelic expression proportions of 26 X-linked genes from the RNA-seq data are plotted in the background. On the x-axis are the five individuals. Plotted on the y-axis is the proportion of expression from the horse allele. (B) The donkey/paternal expression proportion (1-horse) of XIST transcript in five female mule chorionic girdle samples (thick blue line). (C) The donkey/paternal expression proportion (1-horse) of XIST transcript in three female mule chorion samples (thick blue line). The allelic expression proportions of 15 X-linked genes from the pyrosequencing results are plotted in the background. On the x-axis are the three individuals. Plotted on the y-axis is the proportion of expression from the horse allele. (D) The donkey/paternal expression proportion (1-horse) of XIST transcript in five female mule fetus samples (thick blue line). The allelic expression ratios of 13 X-linked genes from the pyrosequencing results are plotted in the background. On the x-axis are the five individuals. Plotted on the y-axis is the proportion of expression from the horse allele.
