Document Summary

Ideology- people my push certain ideologies and have different agendas, to get people exonerated because it"s a part of their genes . Eugenics- if we are able to engineer humans to have good traits, then it would be very controversial. Percent of variance- we have inherent variability in certain variables. Difference between people due to certain cause (in percentages) Heritability: amount of phenotypic (variance we can see- eye colour) in a group due to genotypic variance. Environmentality: amount of observed variance due to environment. Examine correlations between genetic relatedness of family members and personality similarity. Parents and children have 50% of the same genes. Closer relatives should have more personality similarity if the trait is heritable. Monozygotic twins (mz): share 100% of the same genes (identical twins) Dizygotic twins(dz) (fraternal): 50% similarities in the genes, no different than normal siblings. Estimate the similarity between the two types of twins.
