What does Mendel's Principle of Dominance describe?
How larger animals will pass on characteristics more than small ones will

In the mouse Punnett Square, why are there more albino mice than brown mice?
because brown is a pigment, and albino mice have no pigments
because albino genes are dominant
because brown mice are heterozygous
because both of the parent mice are homozygous
