Document Summary
Epigenetics: field of study that may look at how environmental factors relate to gene expression are passed on through asexual division. Looks at heritable changes that occur without changing dna sequence (mutation) Epigenetic changes affect non-reproductive dna or cause changes in cells that. Specific signals can cause incremental changes in gene expression patterns creating differentiated cells (less-specialized cells that have become more- specialized or become more different) Same set of genes but with expression of this gene during diff. life stage. Genetic influence is measured by a statistic called heritability. Heritability: amount of variability in a given trait in a given population at a. Describes proportion of observed variance in a behaviour that can be given time due to genetic factors attributed to genetic differences among people trait that is not inherited has 0 heritability typically heritability estimates for intelligence 50% Studies estimate the heritability of intelligence to be higher for adults than children.
