Question

which of the following cellular phenomena involves the presence of two of everything within a single cell? mitosis binary fission dikaryon meiosis

Explanation:

• Mitosis: A cell division process that results in two daughter cells, each having the same number and kind of chromosomes as the parent nucleus. But it doesn't mean two of everything within a single cell.
• Binary fission: A form of asexual reproduction in prokaryotes where one cell divides into two. Not two of everything in a single cell.
• Dikaryon: A cell or hypha containing two genetically distinct nuclei. So there are two nuclei (a key part) within a single cell.
• Meiosis: A cell division that reduces the chromosome number by half. Results in four daughter cells, not two of everything in a single cell.
