How many cell divisions occur in meiosis
Web8 rows · Meiosis contains two separate cell divisions, meaning that one parent cell can produce four ... WebIn meiosis, there are two rounds of nuclear division resulting in four nuclei and usually four haploid daughter cells, each with half the number of chromosomes as the parent cell. During meiosis, variation in the daughter nuclei is introduced because of random alignment in meiosis I. The cells that are produced by meiosis are genetically unique.
