Q

Chromosomes take the form of chromatin and replicate to produce the 2 chromatids

A

Interphase

16
Q

Chromatin condenses to for chromosomes.

Homologous chromosomes form pairs with synapsis

A

Prophase 1

17
Q

The homologous chromosomes pair along the equatorial plane of the cell so each homologous is on the opposite side of the plane

A

Metaphase 1

18
Q

Homologous chromosomes separate and are drawn to the opposite poles of the cell

A

Anaphase 1

19
Q

Homologous chromosomes reach the opposite pole of the cell and cytokinesis occurs

A

Telophase 1
