The interaction between nature and nurture has been shaping the human mind over millennia. one of the ways science has tried to disentangle nature and nurture is to look at identical twins, both human and animal. just exactly how "identical" are identical twins? they share identical dna they share about the same amount of genes as other siblings their dna is different, but much more alike than other types of siblings

Identical twins may have the same DNA, hence their nature will be the same. However, the character of the different twins may vary because of variations in nurture. This is described as epigenetics which is the effect of environmental stimuli on genetic material without its change in sequence. This affects gene expression due to the differences in DNA methylation and histone modification profiles between the twins.
