1. which step in meiosis is shown in the image below?

prophase i
anaphase i
prophase ii
anaphase ii

Explanation:

In meiosis, during Anaphase I, homologous chromosomes separate and move towards opposite poles of the cell. In Prophase I, chromosomes condense and pair up (synapsis) with crossing - over occurring. In Prophase II (after cytokinesis of meiosis I), chromosomes condense again but there are no homologous pairs (since homologous chromosomes separated in meiosis I). In Anaphase II, sister chromatids separate. In the given image, we can see that homologous chromosomes (chromosomes of the same size and shape, but different colors representing maternal and paternal origin) are being pulled apart towards opposite poles. This is characteristic of Anaphase I.

Answer:

Anaphase I
