in maize, the A locus encodes an enzyme necessary for production of anthocyanin, a purple pigment. At this locus, a functional A allele is dominant to a nonfunctional a allele. Kernels of maize line 1 are completely white. Kernels of maize line 2 are completely white. Pollen from line 1 was used to pollinate female flowers on a plant from line 2 and the ear produced 21 white pigments and 18 purple pigments. what are the parental genotypes of lines 1 and 2? provide an explanation for why the offspring look the way they do? think about transposons.
