i think y xsome disorder rarely happens since y xsome is recessive. think the disorder happens mostly depending on X, we may have an extra X or none.
Is there anyone having another idea, plz post

Um, the y chromosome isn't recessive by any stretch of the imagination.

Up to now, only few Y-linked genes has been identified (holandric genes):

1. resesive gene "wt", causing membranes that appeared between fingers and toes (similar to the ones on frogs or ducks). Its allel, Wt, for normal condition.

2. resesive gene "hg", causing "porcupine man" (long, rigid hairs over the body). Its allel, Hg, for normal condition.

3. resesive gene "h", causing "hypertrichosis" (long hairs on auricles). Its allel, H, for normal condition.

4. genes controlling spermatogenesis

5. testis determining factor (TDF)

6. H-Y antigen

7. some genes for height
