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.

imagine yourself at the junction, where two perpendicular roads meet. you happen to sight someone very adorable at a distance 100m from the junction at the junction. At a given instant that someone is walking at a speed of v m/s. you hope to catch up and try your luck to chat with that person by walking 2v m/s, ALWAYS TOWARDS THE TARGET..what is your PATH ? will you able to catch up with that person?? you have to consider setting up a differential equation...you can simplify the solution of the differential equation by differentiating and then solve the first order diffrential equations.........
