Question

Quizplus · Accepted Answer

Sandra's symptoms suggest she has Turner syndrome, which is caused by the absence of all or part of one X chromosome. This can lead to developmental and physical differences, including short stature, webbed neck, and difficulty with math. XYY syndrome (A) is a genetic condition where males have an extra Y chromosome, which may result in behavioral and developmental differences. Fragile X syndrome (B) is a genetic disorder that affects intellectual and social development and is caused by a mutation on the X chromosome, but it does not involve any missing chromosomes. XXO syndrome (D) is not a recognized genetic condition.
