- Phenotypes can be controlled by many processes besides the actual genotype present. Explain one example of epigenetics that can control phenotype expressionarrow_forwardAn epigenetic study of maternal care in mice was used to study transgenerational epigenetic inheritance. This study found that increased maternal care during childhood resulted in lower stress levels as adults and decreased maternal care with their own offspring. Increased maternal care during childhood resulted in lower stress levels as adults and increased maternal care with their own offspring. Increased maternal care during childhood resulted in higher stress levels as adults and decreased maternal care with their own offspring. Increased maternal care during childhood resulted in higher stress levels as adults and increased maternal care with their own offspring.arrow_forwardOften, the physical characteristics of genetically identical twins become increasingly different as they age, even at the molecular level. Explain why this is so from the point of view of epigenetics.arrow_forward
