the eggs were incubated for the stated time in paraffin oil
||"After nuclei have reached the periphery of the egg to form syncytial blastoderm their total number did not increase further at the same rate. A certain number of nuclei (around 18) migrated into pole cells, where they divided once more at a different rate than that of blastoderm nuclei. Another group of nuclei (about 100) remained in the center of the egg to form yolk nuclei, which continued to divide with a different rhythm. At stage 10, where there should be 512 nuclei altogether, less than 400 nuclei constitute the blastoderm. These nuclei continue to divide synchronously 4 times (not 3 times as has been believed until now) to produce about 6 000 nuclei in the last stage of the blastoderm."
