highly significantP = 1.1 × 10 −30
The negative association between the changes at ZGA and upon Snrpb/d2 overexpression is highly significant ( P = 1.1 × 10 −30 , binomial test), suggesting that higher Snrpb/d2 levels before ZGA maintain alternative exon patterns in a more pre-ZGA state, a trend that was also observed for all exons together (fig.
