Answer 1

let us suppose the disease is colour blindness (it follows criss cross inheritance)

u said that the father was normal .........therefore the phenotype of father would be XY

mother is affected ............phenotype      XcXc

PARENTS                   FATHER       x            MOTHER

                                       XY                                 XcXc

GAMETES                X                Y                     Xc            Xc

F1 PROGENY          XXc              XXc                 XcY             XcY

                           (carrier)         (carrier)           (affected)        (affected)
