Question

Which step in meiosis is shown in the image below?
1070AQ1
Prophase I
Anaphase I
Prophase II
Anaphase II

Answer 1

I don’t see the image — could you upload it? If you can’t, describe what you see and I’ll identify the stage. Useful details:

- Are chromosomes paired as homologous tetrads (two homologs, each with two sister chromatids) or single chromatids?
- Are homologous chromosomes being pulled to opposite poles (whole homologs separating) or are sister chromatids separating at the centromere?
- Is there evidence of crossing-over (chiasmata) visible between homologs?
- How many cells are shown (one cell vs two cells after meiosis I)?
- Are chromosomes condensed and scattered (prophase) or moving toward poles (anaphase)?

Quick identification rules:
- Prophase I: homologous chromosomes pair (tetrads), chiasmata/crossing-over visible, nuclear envelope breaking down.
- Anaphase I: homologous chromosome pairs are pulled to opposite poles; sister chromatids stay together.
- Prophase II: in the two haploid daughter cells, chromosomes re-condense; no homolog pairing.
- Anaphase II: sister chromatids separate and move to opposite poles.

Upload the image or describe it and I’ll tell you which stage it is.
