These puppies were born in the same litter to the same parents, but they have different traits for the feature of toenail thickness. One puppy has thick toenails, one has thin toenails, and the third has medium toenails. How did these puppies end up with toenail thicknesses that are different from one another even though they have the same parents? How did the gene combinations result in the different traits?

Maybe even though they got the same parents it could be dealing with the genetics or the different DNA coming for the parent's genes.
