## Step 1<br />The first question asks for the name of each half of a replicated chromosome. In the context of meiosis, each half of a replicated chromosome is called a chromatid.<br /><br />## Step 2<br />The second question asks for the term used to describe sister chromatids of a chromosome. Sister chromatids of a chromosome are referred to as chromatids.<br /><br />## Step 3<br />The third question asks what happens to the nucleus during prophase I. During prophase I, the nucleus breaks down.<br /><br />## Step 4<br />The fourth question asks what homologous chromosomes pair up to form during prophase I. Homologous chromosomes pair up during prophase I to form a tetrad.<br /><br />## Step 5<br />The fifth question asks where the tetrads line up during metaphase I. During metaphase I, the tetrads line up in the center of the cell.<br /><br />## Step 6<br />The sixth question asks when the homologous chromosomes split up and move toward the opposite ends of the cell. This happens during anaphase I.<br /><br />## Step 7<br />The seventh question asks when two independent cells begin to form. This happens during telophase I.<br /><br />## Step 8<br />The eighth question asks what the division of the cytoplasm to make two new cells is called. This process is called cytokinesis.<br /><br />## Step 9<br />The ninth question asks what the two new cells that are formed from meiosis I are called. These cells are called haploid because they contain half of the chromosome of the original cell that started meiosis.<br /><br />## Step 10<br />The tenth question asks how many cells you had at the start of meiosis I. At the start of meiosis I, you had one diploid cell.
