Ashley is an amateur cytologist who has been given cell samples from 5-year-old identical twin Giordan to analyze. Ashley noticed that there was an extra chromosome in some but not all of the patient’s body cells. However, all of Giordan’s germ line cells showed normal chromosome numbers. In fact, the health chart of the twins revealed that these abnormal cells were absent in all their cells (somatic and germ line) at birth, and all cells of their parents showed normal chromosome numbers. Using your understanding of cellular reproduction - Mitosis and meiosis:
