Physically, no; mentally, that's up to the strength of the individual.
Klinefelters is sex chromosome trisomy. Down Syndrome is trisomy. One of the most common forms of MD is sex-linked and affects boys more frequently than it does girls.
Yes animals do sometimes have Turner's syndrome or Klinefelter's syndrome with similar characteristics as those observed in humans.
Klinefelters Syndrome
Not really. Klinefelter's Syndrome is a genetic issue and as such is NOT preventable at our current level of technology. I guess it may be possible to check the gene of a foetus and abort if the genotype indicates the condition but that is way too harsh a solution as Klinefelters does not necessarily mean a significantly reduced quality of life for sufferers. What is relatively easy to address is the symptoms of Klinefelters and the 'golden standard' for treatment is the application of testosterone. A site that tells you all about Klinefelters is: http://www.klinefeltersyndrome.us/symtomsinboy.html (symptoms in boys) they also have a page on the symptoms in men and another on treatment of symptoms.
No. People with Klinefelter's syndrome have a normal Y chromosome and 2 normal X chromosomes.

Nondisjunction, or sending both chromosomes to one cell during meiosis.
