PLEASE HELP A vase is sitting on a table.
What, if any, forces are acting on the vase? (If there are forces acting on the vase, include what direction they are acting.)

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
