WebIf H = 1, then all variation in a population is due to differences or variation between genotypes (i.e., there is no environmentally caused variation). If H = 0, there is no genetic variation; in this case all variation in the population comes from differences in the environments experienced by individuals. More From Britannica WebEnvironmental factors can also change the epigenome—the chemical tags attached to DNA. These tags cause certain genes to become more or less activate, fine-tuning the amount of protein that's made from them. Diet, toxins, stress, and even physical activity all change the epigenome.
