X Chromosome
The X chromosome’s unique gene balance shapes sex differences and disease risks in unexpected ways

Why do X-linked recessive disorders often affect males more than females?
Because males have two X chromosomes, increasing the chance of inheriting the disorder.
Because females do not carry X chromosomes and are therefore immune to X-linked disorders.
Because males have only one X chromosome, so a single recessive mutation will manifest as a disorder.

The X chromosome's unique role shapes sex determination and genetic inheritance in mammals

Why are X-linked recessive genetic disorders more commonly expressed in males than in females?
Because males have two X chromosomes, increasing the chance of inheriting the disorder.
Because females do not have X chromosomes and cannot inherit X-linked disorders.
Because males have only one X chromosome, so a recessive mutation on it will be expressed without a second copy to mask it.
