Avian zygote activates only maternal allele to disburden high variation of supernumerary sperms contrary to mammal

Here we show that the detailed insight of the onset of zygotic transcription in chicken. Our transcriptomic analysis of early chicken embryo reveal newly expressed and primary transcripts by ZGAs at genome-wide and base resolution. Overall design: Chicken early embryo (Oocyte, Zygote, and EGK.X) samples were investigated based on the whole transcriptome sequencing approach.
