    How do you apply Mendel's law to solve this problem?

    You have three yellow, round peas, labeled I, II, and III, and each was grown into a plant and crossed to a plant grown from a green, wrinked pea. There were 100 peas issuing from each cross were sorted into phenotypic classes as shown below:

    I. 52 yellow, round
    48 green, round

    II. 100 yellow, round

    III. 24 yellow, round
    26 yellow, wrinkled
    25 green, round
    24 green, wrinkled

    What were the genotypes of I, II, and III?

    Solution Preview

    The cross must be

    yellow, round X green, wrinked

    result in

    progeny

    The key cross here to deduce the dominance is II, which have the cross:

    yellow, round X green, wrinked

    result in

    100 all yellow, round

    So the ...
