What would happen if there were no germ-line mutations or genetic recombination possible in a population? (2 points) genetic variation would have to come from random events. only alternate generations would express any genetic variation. body cell mutations would be the only source of heritable genetic variation. there would be no new heritable genetic variation possible in the population.
