a particular trait shows a high concordance in monozygotic twins raised together but a lower concordance in monozygotic twins raised apart. what do these results indicate about genetic and environmental components controlling this trait? |
multifactorial. an example is intelligence with twins. when raised together, they appear to have bigger IQs, than when raised apart. the way they are raised (together/separate) is an environmental factor that affects the trait. the trait can still be similar among the twins because it is genetic and inherited, but the environmental factor affects just how similar and closely related the trait between the twins is |
