completed in 2003. One way to show that genetic inheritance can influence behaviour is by studying twins. There are two types of twins‚ monozygotic and dizygotic. The monozygotic twins are genetically identical as they are the formation of a split fertilised egg and the dizygotic twins are roughly 50 percent identical because they are formed by having two fertilised eggs. The dizygotic twins don’t have to be of the same sex which is useful to psychologists because they can use the different degrees

This paper is an attempt to show why it is a mistake to believe that characteristics that are influenced by genes cannot be changed except by modifying genes. Key terms will be explained Genes are how living organisms inherit features from their ancestors; for example‚ children usually look like their parents because they have inherited their parents’ genes. Genetics tries to identify which features are inherited‚ and explain how these features pass from generation to generation. A feature of a

environment on two sets of twins‚ identical (monozygotic) and fraternal (dizygotic)‚ has come in handy. A number of studies compared identical twins reared separately from birth‚ or close thereafter‚ and found numerous similarities. 1. When examining these two you are looking for concordance rates. Critics of separated twin studies note that such similarities can be found between strangers. Researchers point out that differences in fraternal twins is more common than identical twins. B.

In a Passive genotype-environmental effect‚ the genetically related parents provide a rearing environment that is correlated with the genotype (genetic makeup of an organism) of the child. A child’s environment is correlated with their genes‚ which correlate with their parents’ genes because he or she is making decisions likely from their own preferences. Passive genotype-environmental

genetics as an explanation of eating disorders is based on establishing whether these disorders ‘run in families’. Investigations were carried out on twins‚ both identical (MZ) and non-identical (DZ). In identical twins there was a high concordance rate in anorexia with both of the twins getting the disorder. They were not as high with non-identical twins and in bulimia there was 0% concordance. This indicated that there was a genetic factor involved‚ but also others such as the environment; otherwise
