Mitotic asynchrony in mof¹heterozygotes. Early embryos from 0–2 h were collected from control yw^67c23 and mof¹ mutants and immunostaining was carried out using PH3 antibody (green) which is mitotic marker. DNA was stained with PI (red). A and A’ represents control yw^67c23 while B and B’ represents mof¹ embryos during pre-syncytial and syncytial blastoderm stages respectively. In the case of mof¹ embryos the nuclei are unevenly spaced and not all chromsomes are stained with PH3 indicating the existance of mitotic asynchrony during pre-syncytial blastoderm stage. Bar indicates 10 μm scale.
