Identify the genotype for this pedigree chart

Lets say that the genotypes are:

Male affected:XbY

Male unaffected: XaY

Female  affected: XbXb

Female carrier: XaXb

Female unaffected:XaXa

P: XbY  x  XaXa

F1: XaXb  XaXb  XaY  XaY The middle square is female carrier.

P:XbY  x  XaXb

F1: XaXb  XbXb  XaY  XbY The left square is affected female.

P:XaY  x  XbXb

F1: XaXb  XaXb  XbY  XbY The right square is affected male.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
