- In the following diagram, designate each daughter cell as diploid (2n) or haploid (n).arrow_forwardMitosis produces 2 daughter cells that are identical to the starting cell. Explain how meíosis is different using this diagram to help you. 1) How many cells are created through meiosis? 2) Describe the chromosomes in each gamete at the end of meiosis? Are the set of chromosomes in a gamete identical to the starting cell like they are in mitosis? Are there the same number of chromosomes in each gamete as the starting cell?

Unfortunately, the slides showing the different stages of mitosis and meiosis got mixed up, and some of them got lost. The figures below show the 12 slides that you have managed to find. The organism that you have been studying has a 2n number of 8 with one pair of large metacentric chromosomes, one pair of small metacentric chromosomes, one pair of acrocentric chromosomes and one pair of telocentric chromosomes. a.
