What is the significance of using identical and fraternal twins when studying the effect of the environment on heredity? (please help soon)

Respuesta :

They have the same genetics. So studying two of the same people will allow you to see how they are different, which would be the effect of the environment. (Since genetics are identical.) look up nature vs. nurture.

Since identical twins share the same genetic blueprint, differences between twins must be caused by environmental factors.

Fraternal twins only share 50% of their genes.

Studying identical and fraternal twins allows scientists to estimate how genes and the environment interact.
