A chromosome is
an organized structure of DNA and protein found
in cells. We should all have 46 chromosomes, but sometimes there is a
defect. There are people born with one more. It all depends on which pare there
is an extra chromosome. For example if their is an extra one on the 21st pare
it means that that person has down syndrome.
The x and y pair are there reproductive
pare.
X= Women.
Y= Men.
Women
make X reproductive cells and men makes X and Y. So when the women and man are
reproducing it depends all on the man.
If it
is:
X-X
X-Y
Woman
man
