n the red spotted butterfly there are two traits under investigation.  The wing margin can be either notched (N) or straight (n) and the wing color can be either pale yellow (b) or bright yellow (B).  A bright yellow male with straight wing margins was crossed with a bright yellow female with notched wing margins.  All of the resulting progeny had notched wings and both color patterns were present.  From these data determine the genotypes of the butterflies used in the original cross.
