it's confusing so be ready...
If your puppy is homozygous dominant for a trait, it received a dominat allele for that trait form each parent. Each parent is equally responsible for that part of the puppy phenotype. The same is true for homozygous recessive parts of the puppy's phenotype. Each trai is one-eighth or 12.5% of the puppy's phenotype, so each parent contributed 6.25% for each homozygous dominant or reccessive trait.
Only where the puppy is heterozygous for a trai is only one parent responsible for that 12.5% portion of the phenotype.
Calculate the percentage of th epuppy's phenotype that came from each parent.
