Answer 2

MOST HUMAN CELLS CONTAIN 46 CHROMOSOMES

YOU GET 23 FROM YOUR MOTHER AND THE REST 23 FROM YOUR FATHER.

BUT UNFORTUNATELY , EVERY HUMAN DOES NOT HAVE 46 CHROMOSOMES. AT MOST,THERE ARE MORE THAN 1 MILLION PEOPLE WHO SUFFER FROM DOWN SYNDROME. DOWN SYNDROME IS CAUSED BY IMPROPER CELL DIVISION.IT RESULTS IN AN EMBRYO WITH THREE COPIES OF CHROMOSOME 21 ( THE CHROMOSOME WHICH CONTAINS ABOUT 600 GENES AND INSTRUCTS IN MAKING PROTEINS ) INSTEAD OF TWO .

IT DIFFERS IN EVERY SPECIES

. EG:DOGS HAVE 78 CHROMOSOMES

ONION HAS 16 CHROMOSOMES....etc

HOPE IT HELPS YOU
