Question

In what phase of meiosis are tetrads separated as homologous chromosomes are pulled to opposite poles of the cell?
-Metaphase I
-Metaphase II
-Anaphase I
-Anaphase II

Answer 1

Metaphase I --The pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle.

The centrioles are at opposite poles of the cell.

The pairs of homologous chromosomes (the bivalents), now as tightly coiled and condensed as they will be in meiosis, become arranged on a plane equidistant from the poles called the metaphase plate.

Spindle fibers from one pole of the cell attach to one chromosome of each pair (seen as sister chromatids), and spindle fibers from the opposite pole attach to the homologous chromosome (again, seen as sister chromatids).
