Hemophilia is carried on the X chromosome. If it is passed on to a son it came from its mother. If a daughter inherits it it could have came from either parents or even both. If from the father he himself would have been a hemophiliac. Hope this helps.

Sea stars (or starfish) feed off the oyster beds. If the oyster beds were destroyed it would deplete the major food source of the sea stars and they would begin to diminish.
