Both Klinefelter's syndrome and Down's syndrome are genetic disorders caused by the presence of an extra chromosome.

Genetic disorders are the disease that are caused due to alterations in the genes, also called mutations. These mutations can be addition, deletion, duplication, reversion, etc. These disorders are inheritable from one generation to another.

Klinefelter's syndrome is caused due to the presence of an extra X chromosome in males. Their genetic composition is XXY. This results in development of some female like characters. Down's syndrome is the trisomy (three copies of a chromosome) of chromosome number 21. This happens due to non-disjunction.
