Which is a density- independent factor in controlling a population?
a. shelter
b. access to water
c. predators
d. volcanic eruptions

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).

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
