Solution
The correct option is A XO and XXX
Turner syndrome is a condition that affects only girls and women, results when a sex chromosome (the X chromosome) is missing or partially missing. A girl with Turner syndrome only has one normal X sex chromosome (XO), rather than the usual two (XX). Triple X syndrome (also known as trisomy X, or XXX syndrome, or 47, XXX aneuploidy) is a form of chromosomal variation characterized by the presence of an extra X chromosome in each cell of a human female. Females with triple X syndrome have three X chromosomes instead of two. The karyotype reads 47, XXX because the affected individual has 47 chromosomes, as opposed to the usual 46.
