(A) Lateral views of WT or g9a morphant embryos illustrating the varying degrees of developmental defects observed. (B) Frequency at which the normal/abnormal morphologies are observed in WT or the indicated g9a-MO injected embryos. The mismatch control MO (g9a-mMO) is indicated. (C) Lateral views of WT, znf644a, or znf644b morphant embryos at 48 hpf as well as rescue assays in which the respective cognate mRNA were co-injected. (D) The frequency at which the WT or abnormal phenotypes were observed in indicated embryos.
