So, if a researcher compares the similarity between sets of identical twins to the similarity between sets of fraternal twins for a particular trait, then any excess additive genetic mechanisms, in contrast, mix together--a plant that receives one red gene and one white gene might, if the genes are additive, turn out pink.

Nature is the important factor in the development of health problems for example- depression, bipolar etc we cannot denied the important genetic factors the development of mental illness is not entirely genetic for eg in the case of identical twin, if one develops the condition than there will be 50% chance of developing.

In contrast to the biological approach, the behavioural approach assumes that our behaviour is determined by the environment in which we find the two approaches can be investigated by looking at identical twins that have been either raised together or raised apart after being separated at birth. Because fraternal, or dizygotic, twins are 2 separate fertilized eggs, they usually develop 2 separate amniotic sacs, placentas, and supporting structures identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into 2 if twins are a. It is this similarity of environment but difference of genes that makes them a useful contrast to monozygotic twins, whose environments and genes are largely another type of study, comparing mz twins to dz twins, is more commonly done, because there are many hundreds of thousands of such twin pairs worldwide.

That identical twins have the same genetics due to their appearance however this may not be the case and the information on twin studies from depression research maybe be invalid and may not show how genes cause depression also again focusing on environment being the cause rather than genes, it is common that.
