Explanation:
Detailed explanation-1: -During prophase I a cell in meiosis has a 4N genome, meaning there are four copies of the chromosomes.
Detailed explanation-2: -If the normal diploid number of chromosomes is eight. After meiosis I, each cell will have half the number of chromosomes, i.e., 4 chromosomes as meiosis I is reductional division. As each chromosome is comprised of two chromatids, the number of chromatids in each cell will be eight.
