Document Summary

1: physical traits, psychological traits, traits or characteristics that can be made observable, even by technical procedure. Your biochemical properties, your development, your behaviour, and the products of your behaviour ((eg. need to socially interact)) For each genotype, a range of phenotypes can be expressed given environment and developmental factors. Some organisms display well defined behaviour that is genetically programmed, but many aspects of phenotype (expression) are not. Epigenetic inheritance all biological inheritance mechanisms that do not change the dna sequence of the genome. Genes most often work in groups rather than singly. There are approximately 5 proteins in the human body for each gene. Allele variant of a gene; different versions of the same gene. Range of reaction heredity does not rigidly fix behaviour but instead establishes a range of possible developmental outcomes that may occur in response to different environments.
