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). As shown in the diagram of the axial and appendicular skeleton:The Axial Skeleton consists of the: 1  Skull (cranial bones and facial bones).he 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). As shown in the diagram of the axial and appendicular skeleton: The Axial Skeleton consists of the: 1  Skull (cranial bones and facial bones).
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.
To return from a diploid stage to a haploid stage, meiosis must occur. In regard to changes of ploidy, there are 3 types of cycles: 1  haplontic life cycle â the haploid stage is multicellular and the diploid stage is a single cell, meiosis is zygotic. 2  diplontic life cycle â the diploid stage is multicellular and haploid gametes are formed, meiosis is gametic.
