Abnormal chromosome division during mitosis can result in 47,XXX syndrome. Which statement regarding 47,XXX syndrome is FALSE?
A. Those with 47,XXX syndrome have 3 copies of chromosome 47
B. 47,XXX syndrome occurs only in the female sex
C. Those with 47,XXX may have mild intellectual disabilities
D. 47,XXX results in a mosaic phenotype
Homework Answers
Answer:
A. Those with 47,XXX syndrome have 3 copies of chromosome 47
Explanation:
Triple X syndrome results from an extra copy of the X chromosome in each of a female's cells. As a result of the extra X chromosome, each cell has a total of 47 chromosomes (47,XXX) instead of the usual 46.

Observation: Sex Chromosome Anomalies A female with Turner syndrome (XO) has only one sex chromosome, an X chromosome; the O signifies the absence of the second sex chromosome. Because the ovaries never become functional, these females do not undergo puberty or menstruation, and their breasts do not develop. Generally, females with Turner syndrome have a short build, folds of skin on the back of the neck, difficulty recognizing various spatial patterns, and normal intelligence. With hormone supplements, they can lead...

can help me writing a summary please Chromosomal Aberrations and Human Disorders In addition to mutations that alter the information content of a single gene, chromosomes may be subjected to more extensive alterations that occur most commonly during cell division. Pieces of a chromosome may be lost or segments may be exchanged between different chromosomes. Because these chromosomal aberrations follow chromosomal breakage, their incidence is increased by exposure to agents that damage DNA, such as viral infection, X‐rays, or reactive...
