Genes on the X chromosome show different inheritance patterns in males vs females because
- A
Females have two Y chromosomes (YY); their recessive X-linked alleles are always silenced
- Bcheck_circle
Males have only one X (XY); their single recessive X-linked allele is expressed
- C
Females undergo X-chromosome doubling (XXXX); recessive X-linked alleles are masked
- D
Males inherit X chromosomes only from their fathers; recessive alleles skip male offspring
Explanation
X-linked recessive disorders (color blindness, hemophilia) appear more often in males because they're hemizygous (only one X).
