First phase of meiosis
WebMeiosis I is known as the reduction division stage of meiosis because after meiosis I, the two cells create half the parent cell’s genetic material. The whole process of meiosis … WebMeiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes.
