Genetics 0.0 / 5 ? PsychologyBLoAInternational BaccalaureateOther Created by: Lotto65Created on: 18-12-16 11:39 Name two other factors that could influence behaviour other than genes Environmental and physical influence 1 of 35 Give examples of environmental influences Propaganda, influence of parents' tastes 2 of 35 Give examples of physical influences Training, malnourishment 3 of 35 What are behavioural genetics? How genetics and the environment both contribute to individual variations in behaviour 4 of 35 We have inherited 93% of our genes from what? Rhesus macaque monkeys 5 of 35 Is one gene responsible for a complex behaviour? No - it is the building block for a complex behaviour 6 of 35 What do genes do? Give rise to the development of physiological processes that contribute to certain characteristics 7 of 35 What do some scientists think about genetics? An individual may have the genetics for a certain behaviour but it will not manifest without the correct environmental stimuli 8 of 35 How is the diathesis-stress model used to explain depression? Depression is caused by 'genetic vulnerability' and traumatic environmental stimuli in early childhood 9 of 35 Why is there no cause-effect relationship with regards to genes? Genes are complex 10 of 35 What is the 1990 human genome project? James D Watson wanted to identify all 25,000 genes to map the genetic make-up of humans 11 of 35 What does the 1990 human genome project help to explain? Human behaviour and treatment 12 of 35 Can we match specific genes to specific behaviours? No 13 of 35 What do correlational studies do? Establish if there is a relationship but cannot say if there is a cause-effect relationship because IV not manipulated 14 of 35 What are monozygotic twins? Identical twins 15 of 35 How are monozygotic twins created? One egg splits into two 16 of 35 What similarities do monozygotic twins have? Same sex, appearance and genetics 17 of 35 What are dizygotic twins? Non-identical twins 18 of 35 What differences do dizygotic twins have? Different sexes, 50% of genes 19 of 35 What is concordance rate? The correlation between genetic relationship and similarity of individuals for a certain characteristic 20 of 35 What percentage of genes do you have in common with first cousins? 12.5% 21 of 35 What does heritability mean? Genetic similarity 22 of 35 The higher the heritability... The greater the concordance rates 23 of 35 Why are adoption studies useful? To see genetic and environmental similarities 24 of 35 Do adopted children share any genes with foster parents? No 25 of 35 If heritability is high and environmental influence is low, what would the adopted child's behaviour correlate with? More with the real parent than adopted parents 26 of 35 If environmental influence is high but heritability is low, what would the adopted child's behaviour correlate with? More the adoptive parents than the real parents 27 of 35 Are adoption studies representative of the population? No 28 of 35 Why is it particularly hard to separate genetic from environmental influences? Selective placement ( place children with families who are similar to parents) 29 of 35 Research into the environment and genetics has meant researchers can... Determine the extent of genetic influence 30 of 35 What did governments and schools design in 20th century? Tests to indicate someone's intellectual potential 31 of 35 Who was Alfred Binet and what did he design? A pioneer in intelligence who designed a test to improve the French education system 32 of 35 What evidence suggests genetics and environment plays a role in development? Poverty has important influence on the development of children's intelligence 33 of 35 What did Professor Richard J Hernstein do? Published the 'bell curve' idea into whether and to what extent genes and the environment have anything to do with ethnic differences 34 of 35 Who disputed the 'Bell curve' idea? Why? The media as they found it unacceptable that there are intergroup differences in intelligence 35 of 35
With reference to relevant research studies, to what extent does genetic inheritance influence behaviour? 0.0 / 5
