    When crossing alleles for color, you get

    25% pp

    50% Pp

    25% PP

    White flowers are recessive, so there is a 1/4 chance

    And when crossing alleles for shape you get

    25% rr

    50% Rr

    25% RR

    Wrinkled seeds are recessive so there is a 1/4 chance

    Since you are looking for white flowers AND wrinkled seeds, you need to multiply 1/4 x 1/4, giving you a 1/16 chance that the offspring will have these two traits
