A person affected by disease having chromosome complement XXX is having/called

• A. Klinefillter's syndrome
• B. Down's syndrome
• C. Super female
• D. Turner's syndrome

Answer 1

The correct option is C Super female

A person affected by disease having chromosome complement XXX is called as super female.

Triple X syndrome, also called trisomy X or 47,XXX, is a chromosomal abnormality that affects approximately 1 in every 1,000 females. It is characterized by the presence of an additional X Chromosome in each of a female's cells.

Triple X syndrome is associated with an increased risk of learning disabilities and delayed development of speech and language skills. Delayed development of motor skills (such as sitting and walking), weak muscle tone (hypotonia), and behavioral and emotional difficulties are also possible, but these characteristics vary widely among affected girls and women.

Most cases of triple X syndrome are not inherited. The chromosomal change usually occurs as a random event during the formation of reproductive cells (eggs and sperm). An error in cell division called nondisjunction can result in reproductive cells with an abnormal number of chromosomes.

Hence, the correct answer is option C.
