Which of the following is a sex-linked genetic disorder? Down syndrome B) Huntington’s disease C) Hemophilia D) Cystic fibrosis
Answer: Hemophilia
Explanation
Hemophilia is a sex-linked genetic disorder
Because the gene responsible for its development is located on the X chromosome.
Since males only have one X chromosome, they are more likely to be affected by the disorder if they inherit a mutated copy of the gene. Females, with two X chromosomes, can be carriers if they have one mutated copy but still express the normal phenotype due to their other X chromosome.
