Do the cells that meiosis produces have the exact same DNA? Why or why not

The daughter cells each have a random assortment of chromosomes, with one from each homologous pair. They go on to meiosis 2. No, because DNA is replicated in Interphase first and no interphase stage exists after after Meiosis 1.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
