How would you write if a white and red dog gave birth to a white offspring in a punnett square?

In a Punnett square, you would represent the genetic traits of the parent dogs using their alleles. Assuming the white dog has the genotype WW (homozygous) for white fur and the red dog has the genotype Rr (heterozygous for red fur), the offspring would inherit one allele from each parent. The resulting Punnett square would show that all offspring would have the genotype WR, resulting in white fur, since the white allele is dominant over the red allele.
