    The man's father's genotype is tt - because he is a non-taster.

    Therefore the man (a taster) must be Tt

    (the only thing he could have gotten from his father is t).

    His wife's mother is tt (non-taster),

    so the wife (a taster) must be Tt.

    So both the man and his wife (both tasters) have genotype Tt.
