- B. Down's Syndrome
- C. Jacob's Syndrome
- D. Edward's Syndrome
Explanation
Explanation:XXY chromosomes in a male cause Klinefelter's syndrome.This option is not correct. Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21, leading to characteristic physical features and intellectual disability.This option is also incorrect. Jacob's syndrome, also known as XYY syndrome, is a genetic disorder in which males have an extra Y chromosome, resulting in a karyotype of 47, XYY.This option is also incorrect. Edward's syndrome, also known as trisomy 18, is a genetic disorder caused by the presence of an extra copy of chromosome 18. It is associated with severe developmental abnormalities and a high rate of infant mortality.
