Klinefelter syndrome (XXY males):
- It is a chromosomal disorder caused due to an extra X chromosome in males. Thus genotype of individuals is 44 + XXY. They are described as feminized males.
- The extra chromosome is a result of the non-disjunction of the X-chromosome during meiosis.
- The individual is male and has overall masculine development.
- Individuals have harsh voice pitch and under developed testis.
- They are tall with long arms, feminine development (development of breast i.e. Gynaecomastia), and spermatogenesis does not occur, therefore, individuals are sterile.
