Question

At which phase of meiosis, the two cells, each with separated sister chromatids move towards opposite poles?

• A. Metaphase-I
• B. Metaphase-II
• C. Anaphase-I
• D. Anaphase-II

Answer 1

The correct option is A Metaphase-I

Meiosis is the characteristic division of the reproductive cells. It is also called reduction division because it is this, the parent cell produces four daughter cells each having half the number of chromosomes present in the parent cell. In metaphase I, the spindle formation is complete. The bivalents move and arrange themselves on the equatorial plane. The distribution is of bivalents is random so that the individual paternal and maternal chromosomes can face either of the two poles of the spindle. They may remain attached only at the terminal chiasmata. Each chromosome of the bilavents gets attached to the tractile spindle fibers at the centromere.

So the correct option is 'metaphase I'
