Hello, I have a question specifically regarding a photomicrograph of two cells in the process of mitosis. I have answered both questions but I am rather stumbling on the second question and would appreciate any opinions on this matter. I having been endeavouring to better identify the stages of mitosis and meiosis from photomicrographs which is why I am using this question for revision purposes but I am uncertain in my evaluation.

Question 1: State the stage of mitosis shown by the bottom cell of the two, explain your choice.

I believe that the cell is in anaphase, as the spindle fibres attached to the centromeres of the chromosomes shorten the chromatids are pulled to the opposite poles of the spindle which is visible in the photomicrograph.

Question 2; State the stage of meiosis shown by the top cell of the two. Explain your choice and describe why this is not a typical view of the stage in question.

I believe the top cell is on prophase, since the chromosomes increasingly shorten and thicken by supercoiling and condense to become visible. During this phase, spindle fibres emerge from the centrosomes, the nuclear envelope breaks down and the nucleolus disappears also.

I am not sure why this is not a typical view of the stage in question, would it be because the chromosomes are rather bundled together or perhaps is it in relation to the nuclear envelope?

Sorry I am rather struggling here and would be very grateful of any help 👍
