Abstract
Secondary or generative, nuclei undergo multiplication within the gamont''s enlarging primary nucleus, passing through what appears to be a phase of intensive endomitotic polyploidization before being dispersed into the cytoplasm as potential gametic nuclei. Nucleolar material, then produced in abundance within the enlarged primary nucleus, is also dispersed into the cytoplasm. The residue of the primary nucleus is dismembered and dispersed by cytoplasmic flow as the gametic nuclei multiply and gametogenesis proceeds.
