    Key:

    Tay-sachs disease - aa/Aa

    Normal - AA

    Since both parents are heterozygous

    P1 = Aa x Aa

    by doing punett square

    Possible genotypes: AA, Aa, Aa, aa

    75% chance that they will have affected children.

    25% chance that they will have unaffected children if the disease is a recessive.
