Distribution of reads and transcripts among gene types and regions. Total reads belonging to, (a) highly represented RNA species and, (b) low represented RNA species per culture condition. The total reads correspond only to total exon reads in protein-coding genes, while for the rest of the RNA species correspond to the total reads of all the gene regions. The variability of the number of reads belonging to every RNA species among the different embryos of each condition was larger in the in vitro embryos, especially in the presence of serum, compared to in vivo embryos. c Transcript distribution among the different RNA species in the different conditions. d Distribution of reads uniquely mapped among gene regions in the different blastocysts (each blastocyst constitutes a replicate)
