Solution

The genotype of a person having Klinefelter syndrome is 44+XXY. It is caused due to the presence of an additional copy of X-chromosomes resulting in 44+XXY type chromosome complement. The defect appears due to an abnormal egg (22+XX) and a normal (22+X) and abnormal sperm (22+XY). Such persons are sterile males with overall masculine development and some female characteristics (e.g. Feminine pitched voice, development of breast or gynaecomastia).
