Answer 2

Klinefelter, Turner and Down Syndrome

Explanation:

Klinefelter syndrome is a chromosomal condition in boys and men that can affect physical and intellectual development. Most commonly, affected individuals are taller than average, and are unable to father biological children (infertile). Some affected individuals may have differences in their genitalia like undescended testes, unusually small penis, etc. The addition of an extra X chromosome occurs during the formation of reproductive cells (eggs or sperm) in one of an affected person's parents.

Turner syndrome is due to a chromosomal abnormality in which all or part of one of the X chromosomes is missing or altered. While most people have 46 chromosomes, people with this syndrome only have 45 chromosomes.  

Down syndrome also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is usually associated with delays in physical growth, mild to moderate intellectual disability, and characteristic facial features.
