An error in genetic information present in a body cell of a mammal would most likely produce

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).

3. energy generation

4. lower carbon footprint
