Morning Glory plants can have petal size [large (L) or small (S)], and pigment hue [white (W) or blue (B)]. Assume that each trait is caused by a single gene in which one allele is completely dominant to the other.

Look at the table to the right and determine the dominant and recessive alleles for petal size and pigment hue.

Once you've figured those out, you can next determine the genotypes of the parents.
