Answer

Trisomy of 21st Chromosome
Trisomy 21, also known as Down syndrome, is characterized by the presence of an extra copy of the 21st chromosome. This results in a total of 47 chromosomes instead of the usual 46. Individuals with Down syndrome typically exhibit physical features such as almond-shaped eyes, a flattened facial profile, and cognitive impairments.

XXY
Individuals with XXY have a condition known as Klinefelter syndrome, where they possess an extra X chromosome in addition to the usual XY chromosomes in males. This leads to a total of 47 chromosomes. People with Klinefelter syndrome may experience infertility, reduced testosterone levels, and breast development.

XO
Individuals with XO have Turner syndrome, where they are missing one of the X chromosomes, resulting in a total of 45 chromosomes. This condition is only seen in females. Women with Turner syndrome may have short stature, heart defects, and infertility due to ovarian insufficiency.
In summary, individuals with trisomy of the 21st chromosome have Down syndrome, those with XXY have Klinefelter syndrome, and those with XO have Turner syndrome. Each chromosomal abnormality results in distinct physical and developmental characteristics that can impact an individual's health and well-being.
