Hellohi is correct. The answer is B. There is one extra sex chromosome in this particular karyotype.

Remember, the first 22 pairs of chromosomes are also referred to as autosomal pairs, so abnormality in first 22 pairs would be referred to as an autosome abnormality, while abnormality in the 23rd chromosome would be referred to as a sex chromosome abnormality.

This particular case is referred to as "47,XXX" or "Triple-X" syndrome.

Hope that helps! Slight Smile
