Which statement correctly compares metaphase I and metaphase II?

A) in metaphase 2 twice as many chromosomes line up along the middle of the cell as I'm metaphase 1.

B) in metaphase 1 twice as many chromosomes line up along the middle of the cell as in metaphase 2

C) in metaphase 2 twice as many chromosomes are pulled to opposite ends of the cell as in metaphase 1

D) In metaphase 1 twice as many chromosomes are pulled to opposite ends of the cell as in metaphase 2

B

Explanation:

The correct answer would be that in metaphase 1 twice as many chromosomes line up along the middle of the cell as in metaphase 2.

Metaphase generally involves the formation of the metaphase plate and the alignment of chromosomes at the equator of the cell.

At metaphase I, chromosomes align as homologous pairs as opposed to metaphase II where chromosomes align at the equatorial plate singly. It thus means that twice as many chromosomes line up at the equatorial plate in metaphase I when compared to metaphase II.

The correct option is B.
