The figure below shows the chromosomes in a cell for some species at some stage of cell division (\"pretend\" that chromosomes are always visible for this exercise & ignore any nuclear membrane). How many chromosomes do you see? Is this haploid or diploid? Is this cell undergoing mitosis, meiosis I or meiosis II? What \"phase\" of mitosis or meiosis (I or II) is shown here? The figure below shows the chromosomes in a cell for some species at some stage of cell division (\"pretend\" that chromosomes are always visible for this exercise & ignore any nuclear membrane). How many chromosomes do you see? Is this haploid or diploid? As drawn, this cell could be undergoing (circle all that apply) mitosis, meiosis I &/or meiosis II. What \"phase\" of mitosis or meiosis (I or II) is shown here?

Solution

11: There are three chromosomes; each has two sister chromatids.
12: The cell is haploid as it has 3 chromosomes.
13: The given image shows the alignment of chromosomes on the metaphase plate. If it was meiosis, homologous chromosomes would be present in metaphase I and two daughter cells would be there in metaphase II. So, the cell is undergoing mitosis.
14: The image shows presence of chromosomes on the metaphase plate which occurs during metaphse.
