Correct Answer: A
Explanation:
There are 23 chromosomes from your father's sperm and 23 chromosomes from your mother's egg that are in each of your diploid cells. When you make gametes, you will separate your father's and mother's matching chromosomes. But they line up randomly-imagine laying out 23 pennies and then laying out 23 more on top of those twenty three. The chances you would have 23 heads looking at you is 1/2 x 1/2 x 1/2 x 1/2 .........for all 23 pairs. This is not something that happens very often. In often 1/2 to the 23rd power is about 1 in nine million.
