Question

What happens to the bivalent chromosomes in metaphase I?

Answer 1

Meiosis:

1. Meiosis is a kind of cell division that results in the formation of non-identical sex cells.
2. Meiosis I and II are the two subsequent nuclear divisions.
3. Each one includes four key stages.
4. There are four of them: prophase, metaphase, anaphase, and telophase.
5. Metaphase I is the second step of meiosis I and occurs after prophase I.

During metaphase I:

1. Metaphase I draws attention to the alignment of two homologous chromosomes in a single plane in the cell's centre.
2. Through homologous recombination and crossover at chiasmata between non-sister chromatids, metaphase I emphasise the pairing and exchange of DNA between homologous chromosomes.
3. A spindle apparatus arises during metaphase I, and the paired chromosomes align along the cell's equatorial pole.
4. In metaphase I, the bivalent chromosomes align on the equatorial plate.
