Meiosis question

[NE2000]

I hate it when different sources have conflicting information. Anywayz, the question is, does Telophase include cytokinesis or does cytokinesis occur after telophase? As such, in telophase (of mitosis) can we still say it is one cell with two newly formed nuclei or that it is now two cells as nuclear division has essentially concluded; or is it just the one cell?

I don't think one "includes" the other, but I'm fairly sure they occur simultaneously. I doubt they would ask a questions about such a technicality though

My understanding is that cytokinesis immediately follows telophase, and is not included in what we classify as 'telophase'.
It can get tricky, because in reality, the whole process of meiosis is a continuous one as you know...so all these 'phases' labels are used for convenient reference to certain events in the process.

True, I also came across a source that claimed crossing over occurred in early Metaphase I, as opposed to late Prophase I. In the end, VCE Biology, and biology in general I guess, is full of simplifications.

Telaphase is part of the meiosis. Cytokinesis is a different process all together


its like so

Interphase | meiosis/mitosis | Cytokinesis


and I thought crossing over happened in the Anaphase of the first meiosis division???

From my understanding cytokinesis follows telophase. And as for telophase being one cell or two newly formed cells... i would say its still one cell because it hasn't undergone cytokinesis (cytoplasmic division) so it can't be two new cells during telophase.

Can someone please tell me if im on the wrong track?

you're right, in telophase a 'cleavage' forms in between the two cells, but they are still connected.
