Why Are Males More Susceptible to X Linked Disorders

question 14

Multiple Choice

Why are males more susceptible to X linked disorders?

• A) Because males have an XX pairing of chromosomes; therefore, this increases their odds of a disorder.
• B) Because males have an XY pairing of chromosomes and the Y chromosome is more likely to host a genetic disorder.
• C) Because most genetic disorders are connected to the dominant gene and since men have an XY pairing a disorder is more likely to be expressed.
• D) Because males have one X chromosome, and if a recessive gene for a disorder is present, he does not have another X chromosome that may contain a dominant gene to block its expression.
