The answer is anaphase.


Ron is obviously observing cell division - mitosis. Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis.

1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up

2. Metaphase: Chromosomes line up at the center of the cell. The sister chromatids are joined together.

<u>3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.</u>

4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

 

<span>Therefore, sister chromatids being are pulled to the opposite ends of the cell in anaphase.</span>

This type of reproduction produces variety in species.
ruslelena [56]
Sexual Reproductions (i.e. Meiosis)


In Meiosis you have a crossing over stage in prophase I, which will result in the exchange of genetic material + the random assortment at metaphase 1 and 2 increases the variety.

There is approximately 10 billion different ways that a child can look from a mixture of the paternal and maternal genes due to all the random events that happen in meiosis/ sexual reproduction.
