The fact that fraternal twins reared together are more similar in prajna than identical twins reared apart suggests that environmental factors have a greater influence on the expression of prajna than genetics. This is because fraternal twins share approximately 50% of their genes, which is the same degree of genetic relatedness as non-twin siblings, whereas identical twins share 100% of their genes. Therefore, if genetics were the primary factor influencing the expression of prajna, then we would expect identical twins reared apart to be more similar than fraternal twins reared together. However, the observed pattern of greater similarity in fraternal twins reared together suggests that environmental factors, such as shared experiences and upbringing, may be more important for this trait.
