Document Summary
Determine the percentage of individual differences in a trait that can be attributed to genetic differences and percentage that can be attributed to environmental differences. Determine precisely where in the environment the environmental effects exist (diff teachers students are exposed to) Genetics- the branch of biology that deals with the mechanisms of heredity. Chromosomes- structures that contain dna molecules in the form of genes. Genes- the biochemical units of heredity that govern the development of individual life. Contribute more directly to physical traits than psychological characteristics. When raised together monozygotic are more similar than dizygotic. Twins raised apart are almost similar to each other as those living in the same home. Heritability 2(rmz-rdz)- proportion of observed variance in group of individuals that can be explained or accounted for by genetic variance; proportion of phenotypic variance that is attributable to genetic variance.
