| The arrow points to a mitotic figure cleaving off a narrow cell from a semi-regular hexagon cell. |
| After 10 mitotic divisions, the tip of the hypha bends to form a crozier into which migrates one nucleus of each mating type. |
| The mitotic activity was focally brisk, with an average of 8 to 10 mitoses per highpower field in these areas. |
| The most distal cells undergo mitotic proliferation and serve as a stem-cell population. |
| Each haploid cell undergoes a mitotic division to produce the generative and vegetative nuclei. |
| The structures of rearrangements were defined by mitotic chromosome staining as well as by genetic and polytene chromosome analysis. |
