Pls help! Will give brainliest! A mutation is the change in a gene. Mutations happen when a mistake is made when a cell’s chromosomes are copied. How might mutations introduced to variation into a population?

the dark variety, as they are not visible on the dark tree barks

explanation:

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).
