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.
