Solution
The correct option is A Three
Mitosis is equational division and meiosis is reductional division. Both consists of 4 phases, namely prophase, metaphase, anaphase and telophase. Prophase is the first phase of both mitosis and meiosis I. During this phase, the chromatin condenses and forms visible chromosomes. The mitotic spindle begins to form, nucleolus disappears, the nuclear envelope disappears. Crossing over synapsis formation occurs during prophase I of meiosis I only. Astral ray formation takes place during metaphase. Centriole duplication occurs during the S phase of the cell cycle.Thus, the correct answer is 'Three.'
