Non-hereditary DNA mutations are not classically understood as representing the individual’s genotype Example: a genotype typically implies a measurement of how an individual differs or is specialized within a group of individuals or a species 4. Phenotype-The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. Example: Not all organisms with the same genotype look or act the same way because appearance and behavior are modified by

Hardy Weinberg Lab I. Purpose: The Hardy Weinberg principle states that the allele and gene frequencies will stay constant from generation to generation as long as no other evolutionary influences come along. The evolutionary influences can be things such as mutation‚ mate choice‚ selection‚ genetic drift‚ gene flow‚ and meiotic drive. Frequency is the proportion of individuals in a certain category relative to the total number of individuals considered. The frequency of an allele or genotype is

neurodevelopmental disorder often paired with unique behavioral abnormalities like hypersociability‚ reduced fear and a tendency to approach strangers. The amygdala is an integral component of the neural network and has been implicated in social phenotype particularly in emotion and fear. Functional magnetic resonance imaging (fMRI) and blood-oxygenation-level-dependent (BOLD) responses indicated abnormal structure and function of amygdala in individuals with WS during face processing tasks.
