Answer:

sex-linked- recessive

Step-by-step explanation:

Sex linked recessive are those traits which are expressed even if one copy of the defective allele are present. They are passed from parents to offspring through X or Y chromosomes.

These disorders are more prevalent in men than women because women have two X chromosomes while men have only one. Females can also get X-linked disorder but they are very rare because female needs two copies of defective gene to develop disorder while men need only one.

For example: As you can see in the example image the gene is passed in daughters too but mostly they are carriers but men develop disease because they have only defective X chromosome that contain defective gene and no counter part to lower its effects.

One of the common x linked disease is hemophilia. You can see the pedigree of Hemophilia that men are getting more effected than women.


Hope it help!
