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.
In a human life cycle, meiosis occurs to produce the gametes. In males, this is once puberty has started and occurs continuously. In females, meiosis begins while they are in the womb, but hormones produced during puberty allows the process to finish. This is the only time meiosis occurs in the human life cycle. To produce gametes. Mitosis on the other hand occurs once a zygote is produced (the result of fertilization) in order to produce an embryo, fetus, and so on.
