Question

Quizplus · Accepted Answer

Monozygotic twins, also known as identical twins, share 100% of their genes, whereas dizygotic twins, or fraternal twins, share about 50% of their genes, similar to regular siblings. Studies comparing these two types of twins have shown that intelligence has a significant genetic component. This is because monozygotic twins tend to have more similar intelligence quotients (IQs) than dizygotic twins, indicating that genetics plays a more crucial role in determining intelligence than the environment.
