Concordance rates support genetic causes for phobias if the rate for identical twins is:

Question

Quizplus · Accepted Answer

If the concordance rate for phobias is much greater for identical twins than for fraternal twins, it suggests a strong genetic component to the development of phobias. This is because identical twins share 100% of their genes, while fraternal twins only share about 50% on average. Therefore, if phobias are more likely to be shared by identical twins, it suggests that genes play a larger role than environmental factors in their development.
