Genes for haemophilia diseases are located on:

Hemophilia is an X-linked recessive genetic disorder, meaning the responsible genes are located on the X chromosome (one of the sex chromosomes). Males are more commonly affected because they have only one X chromosome. Autosomes, mitochondria, chloroplasts, and ribosomes are not the locations of hemophilia genes. This X-linked inheritance pattern explains why hemophilia predominantly affects males and can be carried by females.
