Inter-and intra-antipodal variation is presented for a free-nucleolar developmental stadium in the Avena sativa endosperm. Antipodals of common oat are uni-or multinuclear. Multinuclear antipodals, in a single cell, show nuclei of the same mitotic stage, but this is different for various antipodals. Examples of DNA amplification and anomalies occurring during mitosis are provided.
