The given pedigree analysis can’t be x linked recessive due to following reasons-
  1. X linked recessive is passed from mother to son and never from father to son. (1)
  2. For the  given pedigree to be x linked recessive the mother in first progeny has to be carrier but in that case  they should have 1 carrier daughter, 1 healthy son, 1 affected daughter, and 1 affected son which is not the case.(2)
  3. For all the affected males the disease is being passed on to the son  and for that to happen all the females , even ones who married the affected sons (marked as 6 and 9 in the attached file) have to be carrier. Chances for that are very low.
  4. The given pedigree is a classic case of Y linked inheritance for the disease Hairy ears and Retinitis pigmentosa(3)
