Detailed explanation-1: -It was concluded, among many other things, that identical twins are about 85 percent similar for IQ, whereas fraternal twins are about 60 percent similar. This would seem to indicate that half of the variation in intelligence is due to genes.
Detailed explanation-2: -Knowing the intelligence score of one fraternal twin raised together with their sibling allows predicting the other twin’s score with an accuracy of 55%. For identical twins reared together the percentage goes up to 86%, while for identical twins reared apart the percentage drops slightly, to 76%.
Detailed explanation-3: -Scholars have long studied twins to address the “nature and nurture” question; however, opposing “nature” to “nurture” is misleading. Genes combine with the environment to produce complex human traits. The importance of genes suggested by earlier twin studies has often been confirmed by later molecular genetic studies.
Detailed explanation-4: -Intelligence is a product of complex interaction of heredity (nature) and environment (nurture). There are various which shows that intelligence is the result of heredity (nature) and environment (nurture). A study on twins and adopted children support this.
