In meiosis, a cell splits to form new cells with half the number of chromosomes of the original cell, and produce gametes for sexual reproduction. In mitosis, a cell splits to form two daughter cells, which are genetically identical to each other and to the original parent cell. WebA successful transition from the mitotic cycle to the meiotic program in sporogenous cells is crucial for sexual reproduction. By contrast, when meiosis is bypassed or a mitosis-like division occurs to produce unreduced cells, followed by the development of an embryo sac, clonal seeds can be produced by apomixis, an asexual reproduction pathway ...
