Question

Quizplus · Accepted Answer

The presence of three X chromosomes indicates that the individual has Triple X syndrome (also known as 47,XXX syndrome). This condition usually does not cause any noticeable physical differences or health problems, and affected individuals typically develop as healthy females of slightly above-average height. They may have slightly delayed speech and language development and may be at a slightly increased risk of learning and emotional difficulties, but these effects are usually mild. Masculine characteristics, enlarged genital structures, emotional instability, and sterility are not typically associated with Triple X syndrome.
