How many pairs of chromosomes are there?

Answer 1

Each person has 23 pairs of chromosomes, in total they have 46, though in Science Fiction a fictional 24th pair of chromosomes created a super-race that healed faster, and were stronger.

Downs Syndrome is caused by having 47 chromosomes total, which means that the person has an extra chromosome on pair 21.

The typical number of chromosomes in a human cell is 46 - two pairs of 23 - holding an estimated 25,000 genes. One set of 23 chromosomes is inherited from the biological mother (from the egg), and the other set is inherited from the biological father (from the sperm).
