Using points and examples from the talk, explain why colorblindness and hemophilia occur more often in men than in women.

Humans have 23 pairs of chromosomes—the cell parts that hold genetic information. There are some disorders, such as colorblindness and hemophilia,that occur because of a mutation in the X chromosome. If one of a woman’s X chromosomes is damaged or missing, she has another X chromosome to compensate. On the other hand, if a man’s X is damaged or missing, he will inherit the condition. To sum up, because women have two X chromosomes, they can compensate if one of them is missing or damaged, whereas men cannot. As a result, they are more likely to inherit sex-linked diseases such as hemophilia and colorblindness.
