    The mother didn't have it so she had tt, farther was Heterozygous so he must have Tt, therefore probability 50%. Either that or I read the question wrong.

    Bias caused by these

    B2:
    Food chains

    B3:
    Cloning

    My friend got 0% for the thumb one:
    She said that Tt means they are a carrier like the father, and for them to get the disease it would have to be TT.

    I got 50% though!!!
