The illustration below shows the steps of meiosis I. The steps of meiosis 1 are shown. In step A, the chromosomes pair up. In step B, the homologous pairs line up for separation. In step C, the pairs are separated. In step D, sister chromatids stay together. In step E, 2 new cells are formed.

What is the step that is labeled D?
metaphase I
metaphase II
telophase II
telophase I

Telophase I

Explanation:

Meiosis is a kind of cell division employed by sexually-reproducing organisms to produce gametes. It involves the production of four daughter cells (gametes) that each have a reduced number of chromosomes as the parent. Meiosis occurs in a two step division (meiosis I amd II), that involves four major steps each viz: Prophase, Metaphase, Anaphase, and Telophase

In meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) are involved in the steps.

Prophase I- Homologous chromosomes pair up to form a TETRAD structure called synapse. This describes step A

Metaphase I- Homologous chromosomes line up at the cell's equator in order to be pulled apart by spindle microtubules. This describes step B

Anaphase I- Homologous chromosomes are pulled apart to opposite poles of the cell. This describes step C.

Telophase I- Each homologous chromosome consist of two sister chromatids, which remain together in opposite cells. This describes step D

Step E described Cytokinesis, which is the separation of the cell into two daughter cells.

Hence, step D is the Telophase I stage.
