How can mitosis be a form of asexual reproduction?
In mitosis, a diploid set of nucleus goes through Interphase and its DNA doubles for future requirements. As the cell goes through the stages of mitosis (prophase,metaphase,asaphase and telephase), its chromosomes are doubled and within it, forms gradually a new nucleus. So in telephase,we get a cell with two nuclei and then the cell goes through cytokynesis,the cytoplasm is divided and a new cell is formed.
For uniceller organisms,the daughter cell fromed from the parent cell is the offspring of the organism.
