Identical Twins May Not Be So Similar After All, Even if We Go by Just Genes
Identical Twins May Not Be So Similar After All, Even if We Go by Just Genes FOLLOW US ON: Identical -- or monozygotic -- twins come from a single fertilised egg that splits in two. They are important research subjects because they are thought to have minimal genetic differences. This means that when physical or behavioural differences emerge, environmental factors are presumed to be the likely cause. But the new research, published in the journal Nature Genetics, suggests that the role of genetic factors in shaping these differences has been underestimated. "The classic model has been to us...
