Chromosomes are long strands of DNA. Chromosomes contain genetic information that dictates all characteristics of the organism, from hair color to height.
In humans, chromosomes can be found in the nucleus (command center) of the cell.
Humans [normally] have 23 pairs of chromosomes - half of the set comes from the mother and half comes from the father.
One of these sets of chromosomes determines whether you are a male or female. The sperm from the father contains either an X chromosome OR a Y chromosome. The egg from the mother only has an X chromosome. Therefore, the father determines the sex of the child. Female = XX, Male = XY.
