| Questão | Responda |
| Identical twins are referred to as what? | Monozygotic (MZ) |
| Non identical twins are referred to as what? | Dizygotic (DZ) |
| What % of genes are shared by MZ twins? | 100% |
| What % of genes are shared by DZ twins? | 50% |
| Define a twin study | Using correlation research to establish a genetic argument for the origin of human behaviour. |
| Would 2 MZ or 2 DZ twins who've been reared together be more similar according to the bioloigcal approach. Why? | 2 MZ because they share 100% of their genes. |
| If a characteristic were entirely a product of our genes what would we expect from MZ twins? | That both would always share this characteristic. This is NOT the case. |
| Give a strength of twin studies (applicability) | There's lots of data in support of biological roots of disorders which as helped psychologists prevent stress for those vulnerable. |
| Give a weakness of twin studies (2 measurable) | It's hard to isolate whether it's nature or nurture. 1. twins might have experienced a similar environment during separation. 2. Rarely separated at birth so often spent some time together. |
| Give a weakness of twin studies (MZ vs DZ) | Adults tend to treat MZs more similarly as they look more alike. This may lead to their similarity rather than genes. |
| Define a twin study in simple terms | Comparing specific characteristics of identical/non-identical twins. |
