MEIOSIS EDITION!

MEIOSIS I

1

Homologous pairs line up in the middle of the cell. Who AM I?

METAPHASE I

2

My job is to pull apart homologous chromosomes toward opposite poles.

ANAPHASE I

3

I’m the final step of Meiosis I, where two new cells form, each with half the chromosomes.

TELOPHASE I/CYTOKINESIS

4

I’m the whole round of division that separates homologous pairs, reducing the chromosome number by half.

MEIOSIS I

5

I’m the special event that makes sure offspring have unique gene combinations, but I only occur in Meiosis I, not in Mitosis.

CROSSING OVER

MEIOSIS II

1

Sister chromatids line up single file in the center of the cell.

METAPHASE II

2

Now I’m separating sister chromatids to opposite poles — not homologous pairs anymore!

ANAPHASE II

3

I begin right after Meiosis I, but this time, there’s no DNA replication before I start.
Who am I?

PROPHASE II

4

I end the process, forming four new haploid cells that are all different.
Who am I?

TELOPHASE II/CYTOKINESIS

5

I’m the stage where nuclear membranes reappear and spindle fibers disappear — completing the creation of four haploid cells.
Who am I?
