Why are X-linked conditions more common in men than in women? Group of answer choices 1. men acquire two copies of the defective gene during fertilization.   2. men need to inherit only one copy of the recessive allele for the condition to be fully expressed.   3. the sex chromosomes are more active in men than in women.   4. the genes associated with the sex-linked conditions are linked to the Y chromosome, which determines maleness.
