The figure below shows the chromosomes in a cell for some species at some stage of cell division (\"pretend\" that chromosomes arc 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

Ans 15. As seen in the diagram, there are 12 chromosomes in 6 pairs.

Ans 16. The cell is diploid because chromosomes are paired. This we call 2n cell.

Ans 17. The cell could be undergoing either mitosis or meiosis II because the cell is 2n.

Ans 18. The stage is prophase of mitosis/meiosis II as there are randomly arranged, full-fledged and paired chromosomes visible in the cell.
