The axial and appendicular skeleton is shown in the diagram on the right. The axial skeleton is shown in a bright yellow/green colour and the appendicular skeleton is shown in pink (or pale purple, depending on your display and settings).

Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
1 Meiosis occurs in diploid cells. 2  The chromosomes duplicate once, and through two successive divisions, four haploid cells are produced, each with half the chromosome number of the parental cell.3  Meiosis occurs only in sexually reproducing organisms. Meiosis occurs in diploid cells. 2  The chromosomes duplicate once, and through two successive divisions, four haploid cells are produced, each with half the chromosome number of the parental cell.
