23 i think

There's no such thing as "a DNA. But it works the other way around: DNA doesn't contain chromosomes, but chromosomes contain DNA.

A person has 23 chromosome pairs: 46 chromosomes. One (pair) of which decides gender. Some people aren't perfect and have 47 chromosomes. Maybe other 'combinations' exist too.

That would depend on the organism. In humans, it would be 46 chromosomes with thousands of genes.
