In a given species of flowering plant, the colour of the seeds is exclusively determined by the colour of its seed coat. Seed coat colour in this species is governed by a nuclear gene with two alleles. The WHITE (W) allele is dominant over brown (w) allele. If a plant with brown seeds (w w) is crossed as a female with pollen from a white seed ( W W ) plant, what will be the seed colour and the genotype of the embryo
