In certain set of lab mice, black hair(B) is dominant to white hair (b), and coarse hair (C) is dominant to fine hair (c).The Punnett square below shows a cross between a heterozygous black, fine-haired mouse and white heterozygous, coarse mouse

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
