Question
A normal human cell has _____________ sex chromosomes
- 22
- 2
- 23
- 46
Hint:
2
The correct answer is: 2
Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father.
Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born. They are called sex chromosomes:
Females have 2 X chromosomes.
Males have 1 X and 1 Y chromosome.
