WebJun 1, 2024 · Cycles with absent or incomplete karyokinesis can both yield increased nuclear size and ploidy. Cycles with full nuclear division but incomplete cytokinesis, as well as cell–cell fusion, increase the number of nuclei. Each blue arrow represents a doubling in genome content. Each black arrow represents an incomplete cytokinesis. WebJul 21, 2024 · The cells solve their multinuclearity by a stretchy cytokinesis process with cytosolic bridge formation when adherence resumes.
